Eocene Leaf Fossil with Insect Holes

 

Unidentified leaf fossil found in the Florisant formation of Teller County Colorado USA. This fossil is special in that it has three places on the leaf where there is predation. The darker areas show signs of the leaf repairing itself. The fossil dates to the Eocene Epoch. The leaf is about 3.5 cm in length.

Thanks to Kenny for the image.

Calymene Trilobite Imprints

 


Over ten years ago while digging the footers for a sun room addition to the house, I found large rock about the size of a volleyball.  I believe this is rock is Brassfield dolomite while Osgood Shale is found in the area as well.

The imprint of the fossil appears to be a Calymene trilobite that is about 6 cm long. It dates to the Middle Silurian Period. It was found in Jefferson County, Kentucky, USA.


 

To save space it occurred to me to cut the fossil out but on the other side of rock is a fragment of a smaller Calymene. It is possible there are more imprints hidden in the rock that could be destroyed by cutting. All these years I wait till maybe a technology will emerge that will scan through the rock to reveal more fossils.

Paleontologist Elvira Wood

1920 drawing by Dr. Elvira Wood of the Ceraurus pleurexanthemus trilobite. Published in The Appendages, Anatomy, and Relationships of Trilobites by Percy E. Raymond

In today's post I would like to highlight a research paleontologist named Dr. Elvira Wood (1865-1928). From what I can find in public records on the Internet, Dr. Wood was a paleontologist who was active in the late 1800s till the 1920s. Her contributions to paleontology were in organizing, interpreting, illustrating, teaching about, and publishing fossils from university and museum collections.

How I became associated with her work was reading her master's thesis at Columbia University published in 1909 on Dr. Gerard Troost's lost fossils. Without it, Dr. Troost's major manuscript on Tennessee fossils completed weeks before his death might never have been published. More than likely  it either would have been lost or still sitting in an museum archive. Thankfully, Miss Wood was able to get it updated and published 60 years after it had been completed. 

My interest in Gerard Troost (1776-1850) was as a volunteer at the Louisville Science Center (LSC) which housed his mineral collection. The collection was purchased by the Louisville Public Library in the 1870s and was later transferred to the science center. I believed the collection is now at the Indiana State Museum. He also had a large fossil collection of which a few fossils (unlabeled) might still be at the Kentucky Science Center (aka LSC). The fossils that Dr. Wood published descriptions about in her thesis should be stored at the Smithsonian. The rest could be lost to time or somewhere in Nashville, Tennessee.

I could not find a picture of her to lead off this posting so I have placed an illustrations of a fossil she created an image of. There is a picture in the MIT Museum collection of female students in 1893 at Margaret Cheney Room in which she may in [See NOTE 0 below].

Early Life

Her father served in the 26th Regiment of Maine Volunteers during the American Civil War from 1861-1863. She was born in the town of Gouldsboro, Maine on February 11, 1865. In 1872, when she was 7 years old, her parents moved to Boston, Massachusetts. Years after the war, he operated a carpenter and builder shop at 465 Blue Hill Avenue in Boston till his death in 1883 [See NOTE 1 below].

As of yet not been able to find a picture of Elvira Wood but this drawing is from the MIT 1896 Technique yearbook which depicts the fashion of the time.

Education

At age 17, she graduated from the Girls' High School of Boston on June 1882 [See NOTE 2 below]. She then entered the State Normal School at Framingham, a teacher training school now known as Framingham State University. After graduation, Elvira then enrolled in the Massachusetts Institute of Technology (MIT) as a special student in 1893, taking courses in geology, biology, and chemistry. In 1896, her class graduated but she is not listed as getting a degree, instead she became instructor in paleontology at MIT. During her MIT years, the yearbooks show she was active in Eta Sigma Mu (a secret female student group) that later became The Cleofan and the Geological Society.

MIT Research

Elvira Wood named this new crinoid fossil species Gennaeocrinus carinatus from the Hamilton formation of Charlestown, Indiana in an October 1901 publication

In October 1901 she published a paper naming a new crinoid species Gennaeocrinus carinatus. The paper was prepared at the laboratory of the Geological Department of MIT and she thanks Professor William H. Niles for the opportunity to do this. As it turns out, this holotype fossil now resides at the Museum of Comparative Zoology at Harvard University (IP 108317 BSNH catalog number 13327, MUSE locality number 949, previous number 3342). MIT must have transferred their fossil collection to Harvard at sometime in the near past.

She sent a signed copy of this paper to Professor Alpheus Hyatt (1838-1902) which is now in the Harvard library of the Museum of Comparative Zoology. When Google scanned their old books collection the system recorded Ms. Wood's note and signature (see below). The Harvard library shows receiving it in October 15, 1902. Hyatt estate must have given his library to Harvard several months after his death on January 15, 1902. She taught at MIT until February 1903.

Working At USGS

Ms. Wood accepted the post of paleontological assistant to Director of the United States Geological Survey (USGS) who at the time was Dr. Charles D. Walcott (1850-1927). In the following year, she received a regular appointment as Geologic Aid of the USGS. On June 29, 1905, the El Paso Herald newspaper under the headline Geological Survey Work printed "The preparation of monograph on Cambrian brachiopods by C.D. Walcott, assisted by Miss Elvira Wood." 

This image is of the actual fossil that Elvira Wood named in 1904 from the Smithsonian National Museum of Natural History database of USNM PAL 26395 of holotype fossil of Megistocrinus tuberatus. It has a title IRN 3125621. It is listed as having Other Content – Usage Conditions Apply if one wants to use the image for educational, non-commercial use. This image is available at this link https://collections.nmnh.si.edu/search/paleo/?ark=ark:/65665/3d7e06d00e5ae4b1aaf7f73d1ea56d437

In 1904 she published On New and Old Middle Devonic Crinoids which was the culmination of research on fossil specimens submitted to her for study by Assistant Curator Mr. Charles Schuchert. She named two new crinoid genus (Tripleurocrinus and Tylocrius) and seven new species (Megistocrinus tuberatus holotype USNM PAL 26395, Megistocrinus regularis syntype USNM PAL 36013, Megistocrinus sphaeralis holotype USNM PAL 26397, Tylocrinus novus holotype USNM PAL 35150, Dolatocrinus costatus  holotype USNM PAL 26396, and Dolatocrinus asterias USNM PAL 36023). In July 1911, Frank Springer published a document Some New American Fossil Crinoids in which he changed the identification of Tripleurocrinus levis to Myrtillocrinus levis. Its holotype fossil is still stored at the Smithsonian National Museum of Natural History USNM PAL 35146 along with the others mentioned above.

Ostracod fossil Aluta woodi named by Dr. Charles D. Walcott after Elvira Wood in 1913

While working for Dr. Walcott, he named an ostracod fossil after her in 1905 called Bradoria woodi. In 1913, he would rename the same Chinese ostracod for her called Aluta woodi plus another fossil documented below. Miss Wood started revising Dr. Troost unpublished manuscript at Professor Charles Schuchert (1858-1942) of Yale University's suggestion while working at the USGS. Dr. Schuchert was apprentice to Dr. James Hall, later worked at the USGS (1893-1894) and curator U.S. National Museum (1894-1904). One can wonder how Schuchert knew about the Troost manuscript, from Hall or the Smithsonian? When it was published in 1909 she thanked Walcott for 39 photographs used in the publication. She also thanked Dr. Ray S. Bassler (1878-1961) of George Washington University for photographic illustrations. This appointment was changed to that of Assistant Geologist in June 1907. 

Graduate Studies At Columbia University

In the same year she resigned from the USGS and started working at Columbia University. Once there she taught paleontology and assisted at the summer session. In September 1907, she began studies as a graduate student and she received a Master of Arts degree in May 1908 [see NOTE 3 below] with her thesis  "A Critical Summary of Troost's Unpublished Manuscript on the Crinoids of Tennessee." When the thesis was published she thanked Dr. Amadeus W. Grabau (1870-1946) for valuable advice (maybe he was her thesis advisor?). 

Adolphus Heiman drawing of a reconstructed Crinoid Calyx fossil of an Actinocrinus magnificus meant to be the title image for Gerard Troost's Crinoids of Tennessee monograph probably completed in 1849. The original fossil is at the Smithsonian PAL 39900. Elvira Wood wrote about this specimen in her Master's thesis.

In 1909, Dr. Grabau (Professor of Palaeontology in Columbia University) along with Dr. Hervey W. Shimer (Assistant Professor of Palaeontology in MIT) published the North American Index Fossil book Volume 1. He thanks Elvira as one of his students for helping with its publication. Her copies of volumes 1 and 2 are at the Harvard University Library of the Museum of Comparative Zoology (donated on May 10, 1932 years after her death) [LINK]. See image below of the donation label and on the next page her signature from Volume 2.



She received her PhD in August 1909 with the thesis entitled The Phylogeny of Certain Cerithidae [see NOTE 4 below]. When it was published she thanked another female paleontologist Dr. Carlotta J. Maury (1874-1938) "for the loan of Oligocenic shells from the Paris Basin" and Dr. Grabau of Columbia University "for many helpful suggestions" in the acknowledgements. It also lists she presented the abstract to the New York Academy of Science on February 7, 1910.

Paleontology Career

She accepted the position as Curator, Geological Department, Columbia University, where she remained two years, resigning this position to accept the position of Assistant Curator in Paleontology, Museum of Comparative Zoology at Cambridge, Massachusetts in October 1911. In 1912, she worked on labeling the crinoids fossils in the collection as well updating the card catalogue of crinoid fossils. 

In 1913, the Carnegie Institution of Washington published Research in China in Three Volumes and Atlas Volume Three The Cambrian Faunas of China by Charles D. Walcott. On pages 60-61, anthozoa Coscinocyathus elvira is shown from the  Ki-chóu formation, south of Wu-t'ai-hién, Shan-si China. It dates from the Middle Cambrian Period. Walcott writes, "The specific name is given in recognition of the work of Miss Elvira Wood in connection with the preliminary study of the Cambrian fauna of China." Later in the publication, he names a fossil ostracod Aluta woodi and Walcott explains on page 228 "The specific name is given in recognition of the excellent and thorough preparatory work that was done by Miss Elvira Wood in the preliminary study of the Cambrian fossils from China and her work upon the Devonian crinoids."

Cactocrinus proboscidalis crinoid calyx fossil from The Use of Crinoid Arms in Studies of Phylogeny by Elvira Wood plate I figure 1 photo by W. E. Rowe Heliotype Co. Boston 1914

In 1914 she published "The Use of Crinoid Arms in Studies of Phylogeny" in the Annals of the New York Academy of Sciences Volume XXIV. In this article, she named new crinoid fossils Cactocrinus baccatus and C. platybrachiatus. The New York Academy of Sciences also elected Dr. Elvira Wood of the Museum of Comparative Zoology as a Fellow on December 21, 1914.

She continued to curate the paleontology collection at Harvard until 1914 when it is reported "Owing to ill health, Miss Elvira Wood's work was limited to the assortment of considerable series of fossils received from the Boston Society of Natural History." Next year's report said "Miss Elvira Wood resumed her work on 1 December 1915, and during the remainder of the year, she was engaged in revising the identification and arrangement of the study series of Tertiary Gastropoda."

Dr. Wood is mentioned one last time in the Annual Report of the Director of the Museum of Comparative Zoology at Harvard 1916-1917 with the entry "Miss Elvira Wood was employed for eight months and continued the revision and arrangement of the study series of Tertiary Gastropoda."


1920 drawing by Dr. Elvira Wood of the Calymene senaria trilobite. Published in The Appendages, Anatomy, and Relationships of Trilobites

The Appendages, Anatomy, and Relationships of Trilobites by Percy E. Raymond, Ph.D. Harvard published this work in December 1920 to the memory of Charles Emerson Beecher (1856-1904). Dr. Elvira Wood has a large number of trilobite illustrations on this publication. Dr. Raymond writes,  "I am greatly indebted to Doctor Elvira Wood for the care and skill with which she has worked up these restorations from my rather sketchy suggestions. She has put into them not only a great amount of patient work, but also the results of considerable study of the specimens." The trilobite images are displayed throughout this blog post and were published 100 years ago last month.

1920 drawing by Dr. Elvira Wood of the Isotelus maximus trilobite. Published in The Appendages, Anatomy, and Relationships of Trilobites by Percy E. Raymond

It appears she left Harvard after 1917 and went to work at the American Museum of Natural History on trilobite models. In their annual report for 1920 she is still working with trilobites. In her last published book is this quote: "Her last position was Assistant Curator in Paleontology, American Museum of Natural History, New York City, which she was obliged to resign on account of an accident, which made her an invalid for the remainder of her life." [See NOTE 5 below] In her obituary published in an MIT journal states, "In 1917 she became assistant to the curator of the American Museum of Natural History in New York City, but was the victim of an accident during that year which made her a permanent invalid, and since 1917 she has been living in Waltham." [See NOTE 6 below]

Forced Retirement Due to Accident

The last entry in the newspaper database about her is from August 4, 1921 Bangor Daily News (Maine) which wrote "Dr. Elvira Wood and sister of Waltham, Mass. are occupying Finch Lane cottage. Dr. Wood will address the Girl Scouts on Nature Study at East Sullivan, date to be announced."

Winifred Goldring (1888-1971) in The Devonian Crinoids of the State of New York Memoir 16 published 1923 thanked Dr. Wood for help getting specimens and allowing her to use plate images from earlier publications. Note: Dr. Goldring became the first woman in the United States to be appointed a state paleontologist (New York).

Dr. Wood's trilobite images appeared in two more papers: in 1924 by Dr. Raymond entitled New Upper Cambrian and Lower Devonian Trilobites from Vermont and in 1925 Some Trilobites of the Lower Middle Ordovician of Eastern North America. The last paper contains some impressive illustrations of trilobite fossils.

Up until she died it appears Elvira continued to work documenting the Wood family tree. In her final book, she mentions travel to interview relatives as early as 1916 and lists dates of events happening to family members till 1928.

Death

She died at the age of 63 on December 29, 1928 and was buried at the family plot in Mount Feake Cemetery Waltham, Middlesex County Massachusetts USA. Her father George W. Wood (1833-1883), mother Elvira K. Whitaker Wood (1837-1916), sister Amanda (1859-1932), brother Gleason (1867-1941) and his wife Lena (1868-1946) are buried there as well. In 1930, two years after Dr. Wood's death, her book documenting the Wood family history was published The Ancestry and Descendants of Ebenezer Wood of West Gouldsborough, Maine. From reading the book, she notes it originally just started as a small endeavor documenting her family history but turned into a larger project over time. 

In 1931, the librarian at Harvard's Museum of Comparative Zoology writes, "A small collection of books and pamphlets from the library of Miss Elvira Wood, who worked on the collection of fossils here some twenty years ago, were received through the kindness of her brother." [see NOTE 7 below] Years later, Google digitized one of the books donated, below is image of the library label from North American Index Fossil book Volume 1.

Fossils Named by Dr. Wood

 She named her first fossil in 1901's A new Crinoid from the Hamilton of Charlestown, Indiana. The crinoid fossil was called Gennaeocrinus carinatus. As of February 2021, the holotype showed up in the specimen database of the Museum of Comparative Zoology at Harvard University.

Miss Wood named two brachiopod species in her 1901 publication Marcellus Limestones of Lancaster, Erie Co., N.Y. called Camarotoechia pauciplicata and Crania recta. She donated this type fossils to the New York State Museum in 1902.

In 1904's On New and Old Middle Devonic Crinoids, Elvira Wood named two crinoid genus: Tripleurocrinus and Tylocrius and seven crinoid fossil species: Megistocrinus tuberatus, Megistocrinus regularis, Megistocrinus sphaeralis regularis, Tylocrinus novus, Dolatocrinus costatus, Dolatocrinus asterias and Myrtillocrinus levis. As of March 2021, the holotypes are stored at Smithsonian National Museum of Natural History. 

In 1909, she published A Critical Summary of Troost's Unpublished Manuscript on the Crinoids of Tennessee.On page 93, she names a new crinoid species Hydreionocrinus spinosus after the fossil by Wetherby who described it in 1881 as Hydreionocrinus depressus found by Troost. She writes that Wetherby had actually found a new species and thus she names it. It's genus was later changed to Tholocrinus (Kirk, 1939).

Conclusion

While public records have provided a rough time line to Dr. Wood's life, they do not really give any insight as to what motivated her to spend her life in the study of fossils. The 1930 book about her family tree includes an introduction that gives a glimpse of some of her personal perspective on the world. Ms. Wood writes: "The man who said he did not want to look up his family tree for fear of finding a gallows tree had an entirely wrong idea of the true purpose of genealogical research. It should not be undertaken with the sole idea of finding food for vanity in the number of distinguished people we can claim as belonging to us but rather in a spirit of open-minded investigation. If we find evil in our ancestry it is a warning that here is something it is our business to eliminate from the family strain. If we find good it is a challenge to us to equal that plane of experience. More than that, if we are to contribute to the progress of the world we must not only equal the moral attainments of our ancestors, we must excel them. Another fact that is strongly brought out by studies of genealogy is that moral achievement is the only kind contributing to sound social advancement."

At the introduction of her family history book she writes, "When the work was still in its early stages an accident deprived the writer of the power to move about freely, and visiting of libraries and other sources of information became impossible." [NOTE 5 below]. Even with this set back she had an amazing career working with some of the best American fossil collections at the American Museum of Natural History, U.S. Geological Survey, the Smithsonian, Harvard University, Columbia University and MIT. In addition, she corresponded and collaborated with some of the top invertebrate paleontologists of the day. 

She concludes her family's genealogy book with this text:

"This ends the story of an American family from the early days of the settlement of the country to the present time. It contains no celebrated names, no records of shining achievement. Its members were mainly farmers, merchants or mechanics, but they were, with but a few exceptions, men and women of industry, integrity, devotion to duty, and many of them people of sincere religious faith. They possessed the one indispensable attribute of the nation in the past and its hope for the future whether it be held by rich or poor, learned or unlearned; and may the United States of America never lack an abundance of middle class families of this type."

During my research, things I learned

1) Finding all the trilobite images she illustrated. I knew about her work on the Troost fossils from years ago when I worked on his collection. It appears early in her studies, she worked with Paleozoic crinoid fossils, then helped Charles Walcott with Cambrian fossils and finished her career creating a lot of trilobite fossil illustrations and models.

2) Another interesting fact is that she obtained her advanced degrees when she was in her 40s. I am speculating that after high school she trained to become a teacher (maybe specializing in science). She got accepted at MIT to study more advance sciences and while there started working at the Harvard museum. 

3) Learning that she had named a number of fossils and had a few named in honor of her work.

4) Her collaborations with Charles Walcott, Amadeus Grabau and Percy Raymond. I learned more about their careers and scientific contributions.

5) The stories of other female paleontologists working at the time, specifically Winifred Goldring, Carlotta Maury, and Marjorie O'Connell. Women of that time had a lot of challenges especially pursuing careers in geological sciences. Learn more about this period and read about other women paleontologists in the Museum of the Earth's Daring to Dig: Women in American Paleontology on-line exhibit. An upcoming book and web site is being created by author Katherine Dettwyler about Marjorie O'Connell Shearon. Dr. O'Connell wrote a paper in 1914 that renamed one of the largest horn coral fossils (Siphonophrentis) known to have existed that can be found in the Louisville, Kentucky area. She and Dr. Wood have a number of things in common: they both worked at the American Museum of Natual History at the same time, got degrees from Columbia University, and collaborated with Dr. Grabau while there.

Recent Mentions of Elvira Wood's Work

After all these decades, there has been some recent activity involving Dr. Wood, a few papers in 2002 and 2009 referring to Aluta woodi Chinese ostracod fossil Charles Walcott named it after her as well as papers on Troost's fossils. Two papers were written about the lost Troost crinoids which referenced Dr. Wood's 1909 work in 2005 by Kennesaw State University's Julie Newell in Earth Sciences History and Ohio State's William Ausich 2009 paper in Journal of Paleontology. I was glad to see that months ago a Harvard podcast referred to Dr. Elvira Wood and her time working in their museum.

In an August 2020 podcast, Harvard Museums of Science & Culture (HMSC) Connects! entitled 19th-Century Women at Harvard's MCZ with guest Reed Gochberg and hosted by Jennifer Berglund. Dr. Gochberg is the Assistant Director of Studies, History, and Literature at Harvard. Around the 07:19 mark in the podcast Dr. Gochberg says "One woman who worked at the museum in the 1890s named Elvira Wood actually for a while taught as an instructor at MIT. She got her PhD at Columbia, and then she came back to work at the museum in the 1910s for a few years, but she specialized in invertebrate paleontology, and so the work that she was doing at the museum in the 1890s was actually preparing some of the museum's early paleontology displays for public exhibits, and she also donated a number of her own collections, she helped to catalog collections for the museum, and also prepared illustrations and actually published some of her own work."

I would have thought she would have gotten it signed by the authors since she helped them. Also I would have thought it would have been marked up with notes about various fossils she would study or reference for research through her career.

Cambrian Trilobite Olenellus From Boston Area

 


In August 1900,  Amadeus W. Grabau (1870-1946) published Palaeontology of the Cambrian Terranes of the Boston Basin. He described an Olenellus (Burr, 1900) trilobite cephalon fossil on page 665 and shown on plate 34 figure 1a. 

Dr. Grabau writes "Among the material collected by Mr. H. T. Burr at North Weymouth are two very perfect heads of a species of Olenellus which appears to be undescribed... The larger head (Pl.34, fig. 1 a) (as compressed upon the slate) describes almost a semicircle in outline, with the centre at the base of the glabella. Width of head, 47 mm. Length at the centre, 24 mm. The postero-lateral angles project about 4 mm. behind the base of the occipital ring.

The glabella has the form of a n acute triangle, the anterior end forming the bluntly rounded apex of the triangle. The length of glabella is 20 mm., and the width of the occipital ring, 12.5 mm. There are three pairs of glabellar furrows in front of the occipital furrow. the latter is strongly marked for about a third of the distance inward, form the margin of the glabella on each side, and is continued across by a faint depression. It appears more like a pair of glabellar furrows, which are deep and rather wide at the margin, becoming shallower as they pass inward and gently backward... Eye lobes crescentric, relatively narrow."

"No specific name is present proposed for this species which is undoubtedly new, since the material is insufficient to establish a complete specific diagnosis. It probably belongs to a new subgenus of Olenellus." It was found "in the dark purplish Lower Cambrian slates of Pearl Street, Norht Weymouth," Massachusetts.

Figure was drawn by Miss Elvira Wood (1865-1928), Instructor in Paleontology in the Massachusetts Institute of Technology. She drew a large number of  images for this document. On page 694, Dr. Grabau writes "To Miss Elvira Wood and Miss L.R. Martin thanks are due for the care and labor bestowed on the illustrations of the fossils."

Gennaeocrinus carinatus Crinoid Fossil

 



These images are of the holotype fossil of Gennaeocrinus carinatus crinoid. It was named by Elvira Wood a paleontology instructor at the Massachusetts Institute of Technology (MIT) in 1901. The fossil found in the Hamilton Group of Charlestown, Indiana USA. The fossil dates to the Middle Devonian Period. I believe the Hamilton (New York) is compared to the Sellersburg Limestone (Silver Creek and Beechwood limestones).



The Miss Wood observes "This species is remarkable for its elaborate and delicate surface ornamentation, the thin carinae rising at right angles to the surface and sometimes a millimeter or more in height." The genus was named by Wachsmuth and Springer in 1881. The species name appears to be derived from the word "carina" (a keel-like part or ridge, Latin for keel). This holotype specimen now resides at the Museum of Comparative Zoology - Harvard University (Invertebrate Paleontology 108317).




This fossil is the first fossil species she named and would later leave MIT to work with Charles Walcott on Cambrian fossils at the U.S. Geological Survey. Afterwards, she would obtain her Masters and PhD at Columbia University and spend the rest of her career curating at natural history museums and creating paleoart for scientific papers (Columbia University, Museum of Comparative Zoology at Harvard University and American Museum of Natural History in New York).

Paleontologist Ruth Gillespie Browne

 

I live near outcrops of the Ordovician Period Bardstown Reef fossil beds. During 2008-2009, I collected a number of fossil coral specimens and researched more about them. The name of a local scientist appeared during my quest which was Ruth Browne. Unfortunately, I could not talk to her about my finds as she had passed away in 1999 at the age of 94.

An item I believe is missing from the Internet is the lack of a record of women in the geological sciences from the 19th and early 20th century. A remedy to this is to publish some information to help with this situation. Using public records and some Internet databases, I was able to find out more about this Louisville area paleontologist.

Early Life

Ruth F. Gillespie was born on July 28, 1905 in Syracuse, New York. Her mother Ella M. Gillespie (1880-1963) was a housewife. Ruth's father Robert M. Gillespie (1877-1935) was telecommunications engineer. In the early 1920s, Western Electric sent him to Sweden to install a phone system between Stockholm and another city. Ruth and her family applied for passports in 1921 for a 1922 trip to stay with him in Europe. She attended high school in Scandinavian countries where her father worked. Above is a re-touched 1921 passport records image. It appears she, her mother and sister sailed on the SS Stockholm to Europe in July 1922 and returned on the SS Lapland from Southhampton, England (August 11, 1922) to New York City (August 19, 1922).

Education

Ruth graduated from Cornell University in 1929 with a bachelor's and master's degrees in geology with emphasis on paleontology. She had a younger sister Helen E. Gillespie (1907-1983) who graduated from Cornell University with a degree in architecture.

Marriage

She married James Gunn Browne (1905-1995) on August 30, 1930 in Syracuse New York. Below is a picture of James from his 1922 Charlottesville High School (Virginia) year book. Mr. Browne eventually lived in Louisville, Kentucky where he was treasurer in 1948 at Whayne Supply (construction equipment supplier). He was elected to their board of directors in June 1953 and stepped down as their secretary-treasurer in 1969. He would later retire from there as Vice President and  Finance Director in 1970 [source: Building on a Century of Commitment: A History of Whayne Supply Company by Carl E. Kramer Sunnyside Press, 2013]. From best I can tell, after she got married, they lived in Virginia and she raised two children.



Life in Louisville

Later the family moved to Louisville (maybe in the mid to late 1940s). The first instance of her mentioned is in the Courier Journal newspaper database on October 10, 1954 in an article entitled 'Creature Meets Critter At Wildlife Meet' by Kent Previette. It shows a picture of Ruth G. Browne holding a black pilot snake while two other women observe. The caption identifies her as head of the Ohio Falls Chapter of Kentucky Society of Natural History. The article states the society is one of the sponsors of the three-day 15th Annual Wildlife and Natural History Conference.


The next entry in the newspaper database is from October 5, 1961 showing Mrs. Ruth Browne (geologist and director or Kentucky Society for Natural History) leading the 4th grade class of St. Matthews Elementary School on a fossil hunt at the quarry at Brownsboro Road and Hubbards Lane. The police later ended the event citing child safety at the quarry as an issue.

The Courier Journal article from January 28, 1968 profiled her in their Woman in the News column entitled 'Her Museum Cause Is a Site' by Yvonne Eaton (1935-2005). The article mostly centers on the controversy of where Louisville's Museum on Natural History should be located. She favored the site at the Ben H. Collings estate at Newburg Road and Trevillan Way as opposed to downtown site or or the campus of the University of Louisville. It eventually was located downtown where the Kentucky Science Center is now (727 W. Main Street, Louisville). In the article she is identified as a board member of the Louisville Natural History Museum, Inc. and a former teacher at the University of Louisville and a former president of the Ohio Falls Chapter, Kentucky Society of Natural History. The article says she "attributes her love of the outdoors to weekend outdoor trips on which her father took the family. She say that she was taken in a basket even before she could walk to a secluded summer camp which her family owned in the Adirondacks."
Mrs. Browne is quoted in the article, "Geology has just been an interest with me. I think, why do I stay home and work with these bugs. But I enjoy it. I'm not a socialite. It's not that I don't like people. But it's that I feel I can contribute in this way. I have compulsion. I can't explain it. I feel there isn't enough time."

In 1973, she and Dr. Erwin Robert Pohl (1904-1973) of Horse Cave, Kentucky named a fossil foraminifera genus Tubispirodiscus found in the Fraileys facies of the Big Clifty Formation (Chesterian) of central Kentucky.

The Paleontological Research Institution of Ithaca, New York list her has a Trustee from 1976 to 1981. Ruth Browne wrote a number of letters to the editors of the Courier Journal which got published. If not writing about the Louisville museum, the letters were in tribute to people she was associated: Carlyle Chamberlain (1969), Leonard Brecher (1976), and Robert Paul (1982).

In 1981, she testified a U.S. Congressional committee about the importance of preserving and protecting the Falls of the Ohio River area (it is now an Indiana State Park). Public law 97-137 TITLE II - FALLS OF THE OHIO NATIONAL WILDLIFE CONSERVATION AREA approved December 29, 1981.

The last newspaper database entry that mentions her while alive was from July 22, 1991 Courier-Journal article 'WORK OF ART Terry Chase tells nature's story though museum exhibits' by Linda Stahl. In the article,  Ruth Browne is identified as a board member of the Louisville Nature and Conservation Center. She and other board members traveled to Chase Studio, a 125 acres of woods next to a national forest 30 miles east of Branson, Missouri. They were looking at exhibit developer's work on three projects: planned Falls of the Ohio Interpretive Center, the Nature and Conservation Center to be constructed at Joe Creason Park in Louisville, and the American Cave and Karst Center at Horse Cave, Kentucky.

Legacy

Before her death she made a large financial contribution and donated a number of her books to the Falls of the Ohio State Park. Browne's fossil collection and library were donated to the Paleontological Research Institution in Ithaca (now "Museum of the Earth"). She also donated money to the Nature Conservancy and Cornell University in her will. The available literature paints a picture of a very talented and generous person.  The Museum of the Earth database shows a number of specimen donations attributed to her.  

I am grateful she published her coral research as it helped with identification of the eastern Louisville fossils found. In addition, after reviewing newspaper articles and letters to editor over the decades she lived in Louisville, it shows she was a dedicated advocate for museum for natural history and science and other nature centers in the Louisville area.
