Florence Bascom (July 14, 1862 – June 18, 1945) was the second woman to earn her Ph.D in geology in the United States, and the first woman to receive a Ph.D from Johns Hopkins University, which occurred in 1893.[1][2] She also became the first woman to work for the United States Geological Survey, in 1896.[3][4] As well as being one of the first women to earn a master's degree in geology, she was known for her innovative findings in this field, and led the next generation of notable female geologists. Geologists consider her to be the "first woman geologist in this country [America]."[5]

Early life

Florence Bascom was born in Williamstown, Massachusetts on July 14, 1862. The youngest of five children, Bascom came from a family who, unlike most at the time, encouraged women's entrance into society.[2] Her father, John Bascom, was a professor at Williams College, and later President of University of Wisconsin.[6] He was the driving factor of her career and her first contact in the field of Geology.[2] Her mother, Emma Curtiss Bascom, was a women's rights activist involved in the suffrage movement.[7] Her parents were steadfast supporters of women's rights and encouraged women to obtain a college education.

Education

Initially Bascom was not interested in geology. She earned a bachelor's degree in arts and letters in 1882,[5] and a Bachelor of Science in 1884 from the University of Wisconsin. After persuasion from her father and a rejection from another school, Bascom obtained her first science degree, which turned her interest towards geology.[8] In 1887 she obtained her Master of Science degree from the same university. During this time women had limited access to educational resources, such as the library and gymnasium, but also limited access to classrooms if men were already in them. Her professors at the University of Wisconsin, Roland Duer Irving and Charles R. Van Hise, were part of the USGS.[9] Bascom received her Ph.D at Johns Hopkins University. While studying at Johns Hopkins she was forced to sit behind a screen so as not to disturb the men in the class, whose education was the priority.[6] Since Geology at the time was purely a male discipline, Bascom faced many challenges getting her education and establishing herself in her field; this led to her becoming known as the "Pioneer of Women Geologists."[2]

She was the second woman to obtain a Ph.D in Geology. However, she was the first female geologist to present a paper before the Geological Survey of Washington, in 1901.[10] She was also the first woman elected to the Council of the Geological Society of America (in 1924; no other woman was elected for more than two decades).[10] Another notable achievement is that she was the first female officer of the Geological Society of America, and in 1930 became the second Vice-President.[2]

After receiving her B.A in 1884, she started her college teaching career at the Hampton School of Negroes and American Indians (currently known as Hampton University), working there for a year before going back to University of Wisconsin for her master's .

Work

Florence Bascom contributed to a special type of identification for acidic volcanoes. Her journal, The Structures, Origin, and Nomenclature of Acidic Volcanic Rocks of South Mountain, begins by identifying various rock structures formed by the volcano. Bascom argues that South Mountain's rock formations have changed over time, with some rocks originally showing signs of being rhyolite, but now holocrystalline rock. These rocks defy the nomenclature used to identify rocks invented by German and English scientists, so she created prefixes to add to these pre-existing names, to identify acidic changes in rocks. The prefixes she came up with are meta, epi, and apo.[11]

Florence presented a second notable new conclusion regarding the cycles of erosion within Pennsylvania; earlier scientific thought was that the Piedmont province of Pennsylvania was made by two to three erosion cycles, while she had evidence there were at least nine cycles. Florence found this by compiling a strati-graphic record of Atlantic deposit in the province, listing the depth, unconformities, and types of deposition (like sand, clay, or gravel). The cycles occurred over a large period of time, with six cycles occurring in the post-Cretaceous period and three occurring in the Cretaceous period. This conclusion gave scientists new ideas about erosion cycles regarding their rate of occurrence and how to define a cycle. [12]

She also held a career as a teacher. She taught mathematics and science at Rockford College from 1887 to 1889, and later at Ohio State University from 1893 to 1895.[13] She left Ohio State University to work at Bryn Mawr College where she could conduct original research and teach higher level geology courses.

At Bryn Mawr College, geology was considered adjunct in comparison to other natural sciences. Her workspace consisted of a storage space in a building constructed solely for chemistry and biology. Over two years she managed to develop a substantial collection of minerals, fossils and rocks. Bascom founded Bryn Mawr’s department of Geology in 1901. She proceeded to teach and train a generation of young women in this department. In 1937, 8 out of 11 of the women who were Fellows of the Geological Society of America were graduates of Bascom’s course at Bryn Mawr College. In the first third of the 20th century, Bascom’s graduate program was considered to be one of the most rigorous in the country, with a strong focus on both lab and fieldwork. It was known for training the most American female geologists. Her students did not just graduate, they often succeeded in important geology careers for themselves. She was known to set high standards for her students as well as herself. Though she was extremely tough on her students, they were grateful for the quality of education that she gave to them.[2]

Bascom retired from teaching in 1928 but continued to work at the United States Geological Survey until 1936.[6]

Notable mentors

Her father, John Bascom, played a pivotal role in Florence Bascom becoming a geologist, beginning when Florence was 12 and her father moved her and her family from their hometown to accept the position as President of the University of Wisconsin, the university where Bascom would begin her education. Her interest in geology began with her father; she believed "they understood each other" and stated he was "All that [she] needed, association with him gratified all [she] wanted or needed so far as men were concerned." The above quote references the network of male coworkers a woman would have to gain to be respected in a scientific field. It was a drive with her father who pointed out a landscape that she did not understand, that intrigued her enough to learn about the earth and geologic processes. Contradicting her earlier statement she had many other male mentors throughout her career.[2]

Bascom trained under experts in metamorphism and crystallography.[5] Bascom's choice of study was strongly influenced by Roland Duer Irving, a professor at the University of Wisconsin, and Charles R. Van Hise, who was Irving's assistant. In the years she worked under these two, 1884-1887, the Geological Survey in Washington had established a division of glacial geology, motivating her to enter the field of petrography and structural geology. This led Bascom to analyze formations in South Mountain in Maryland. These formations were regarded as sediments but under close observation Bascom arrived at the conclusion that the formations were altered volcanics, which she identified as, "Apor-hyolites". Being an expertise in mineralogy, petrology, and crystallography[14] she used these ideas to create her masters thesis which was finalized and named, "The Sheet Gabbros of Lake Superior."[15]

Death

Bascom died of a stroke (cerebral hemorrhage) on June 18, 1945, at the age of 82.[13] She is buried in a Williams College cemetery in Williamstown, close to family members.[16]

Named in honor of Florence Bascom

Publications

Florence Bascom published over 40 articles on genetic petrography, geomorphology (specifically the provenance of surficial deposits),[5] and gravel.[17] Her own account of her youth in Madison may be found in the Wisconsin Magazine of History with the title "The University in 1874–1887", March 1925.[18]
