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, 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. I could not find a picture of her to lead off this posting so I have placed some illustrations of fossils she created images for in various publications.

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].

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, she became instructor in paleontology at MIT. 

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. 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

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. 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.

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."

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 (1815-1900). 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.

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]

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.

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.

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 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 so many 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."
