Florence Bascom

Florence Bascom (July 14, 1862 – June 18, 1945) was an American pioneer for women as a geologist and educator. Bascom became an anomaly in the 19th century when she earned two bachelor's degrees. Earning a Bachelor of Arts in 1882, and a Bachelor of Science in 1884 both at the University of Wisconsin. Shortly after, in 1887, Bascom earned her master's degree in geology at the University of Wisconsin. Bascom was the second woman to earn her PhD in geology in the United States, in 1893. Receiving her PhD from Johns Hopkins University, this made her the first woman to earn a degree at the institution. After earning her doctorate in geology, in 1896 Bascom became the first woman to work for the United States Geological Survey as well as being one of the first women to earn a master's degree in geology. Bascom was known for her innovative findings in this field, and led the next generation of female geologists. Geologists consider Bascom to be the "first woman geologist in America".

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. Her father, John Bascom, was a professor at Williams College, and later president of the University of Wisconsin. He was the driving factor of her career and her first contact in the field of geology. Her mother, Emma Curtiss Bascom, was a women's rights activist involved in the suffrage movement. Her parents were steadfast supporters of women's rights and encouraged women to obtain a college education.

Her father became the president of the University of Wisconsin in 1874. One year later in 1875, the university began accepting women and Bascom Hill, within the Madison campus, was named after the family and their legacy.

Florence Bascom had a very close relationship with her father and he played a very influential role in her life. Her father had struggled with mental illness and would often take his children exploring into the mountains. These explorations and the various scientific instruments they had in their household encouraged her to have an interest in sciences. Florence graduated with high grades from Madison High School at the age of 16.

Education

Bascom graduated from the University of Wisconsin with two bachelor's degrees. The first degree was in arts which was received in 1882 and the second was a Bachelor of Science in 1884. Bascom also received her master's in geology in 1887 at the same university and this is where she discovered her interest in geology but specifically in the very unknown field at that time - petrography. After completing her master's, Bascom enrolled at Johns Hopkins University when it allowed women to attend graduate school and continued her studies in petrography there. Bascom's thesis was on "A Contribution to the Geology of South Mountain, Pennsylvania". In 1893, Bascom graduated from Johns Hopkins with her PhD, making her the first woman to graduate the university with that degree and the second woman in the United States to earn a PhD in geology.

While attending the University of Wisconsin, Bascom was a member of the Kappa Kappa Gamma chapter and was one of the first members to join an all women's fraternities between 1867 and 1902.

Career

After receiving her PhD, Bascom spent the next two years as an instructor and associate professor at Ohio State University teaching geology. Bascom then went on to Bryn Mawr College and founded the department of geology in 1895 which led to it becoming one of the best departments in the country. Bascom was appointed assistant on the U.S. Geological Survey and later was assigned that section of the Piedmont which lies in Maryland, Pennsylvania and part of New Jersey. In 1899 Bascom went on to teach petrography and by 1906 Bascom became a full professor and had an associate. Bascom spent many summers mapping the schists and gneisses of that area and studied the thin sections of the rocks both during summer and winter. This area of work came with great complexity, however Bascom's work and careful study provided much clarification. Throughout her career of thirty-three years, Bascom continued to work at Bryn Mawr College and retired when the college had just expanded its science building. By 1924, Bascom became a councillor of the Geological Society of America and in 1930 she was appointed as vice-president of that society making her the only woman to have ever held those offices. Bascom's career consisted of her being an editor of the ''American Geologist'', a member of the National Academy of Sciences, the National Research Council, as well as the Geophysical Union and many other scientific societies. Bascom had also written many short papers, some which were in the field of geomorphology. Bascom also taught at Hampton Institute of Negroes and American Indians, today renamed Hampton University (1884–1885), Rockford College (1887-1889) and Ohio State University (1903–1895).

Work

Florence Bascom contributed to a special type of identification for acidic volcanoes. Her article, "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-.

Bascom 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 discovered that there were at least nine cycles. Bascom found this by compiling a stratigraphic record of Atlantic deposit in the province, listing the depth, unconformities, and different grain sizes (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. In 1896, Bascom worked as an assistant for the USGS. Her role in the team was to study crystalline schists in a square degree of area along eastern Pennsylvania and Maryland, as well as a portion of northwest Delaware. For part of her life as a teacher, Bascom simultaneously worked in the geological survey and her work lead to a multitude of comprehensive reports of geologic folios.

Bascom spent a year learning and researching advanced crystallography in the laboratory of Victor Goldschmidt in Heidelberg before going back to teaching as she did not want to spend time doing "overspecialistic research", that she would not be able to teach to her students in the courses offered.

Bascom's specialization in petrography focused on complex layers of rocks and mountains. The formations that took place there had been regarded as sediments previously however, the closer study of it done under microscopes proved them to be altered volcanics and not sediments which Bascom then named "aporhyolites" with the prefix of "apo-".

At Bryn Mawr College, geology was considered adjunct in comparison to other natural sciences. Her workspace consisted of storage space in a building constructed solely for chemistry and biology. Over a two-year period, Bascom managed to develop a substantial collection of minerals, fossils, and rocks. Bascom founded Bryn Mawr's department of geology in 1895 and proceeded to teach and train a generation of young women in this department. 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. Additionally during WW II some of her students were involved in confidential work for the Military Geology Unit in the U.S. Geological Survey. Bascom was known to set high standards for her students as well as herself. Though she was extremely tough, her students were grateful for the quality of education that she gave to them. In 1928, Bascom retired but continued to work at the United States Geological Survey until 1936.

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. It was a drive with her father who pointed out a landscape that she did not understand, which intrigued her enough to learn about the earth and its geologic processes. In addition to her father's influence, Bascom's mother, Emma Curtiss Bascom, was an influential member in the suffragette movement in the 19th century.

Bascom trained under experts in metamorphism and crystallography. 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 Bascom worked under the 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 the discovery of "aporhyolites".

George Huntington Williams (1856–1894): Bascom met George Huntington Williams through her early mentor Irving, and later worked with Williams in field research while she was at Johns Hopkins University. Bascom began her studies at Hopkins, and was told there was a chance she would not get her degree because she was a woman. Williams supported her and she later received her PhD.

Edward Francis Baxter Orton (1829–1899): Bascom worked with Edward Francis Baxter Orton while she was at Ohio State University.

Victor Mordechai Goldschmidt (1853–1933): Bascom studied crystallography under Victor Mordechai Goldschmidt while on leave in Germany in 1906–1907.

Legacy

Florence Bascom left a legacy in part due to her significant scientific discoveries, but also partly due to her legacy of training women geologists. Bascom founded the geology department at Bryn Mawr College and encouraged other women to enter the field of geology. Bascom trained and mentored Louise Kingsley, Katharine Fowler-Billings, petrologist Anna Jonas Stose, petrologist Eleanora Bliss Knopf, crystallographer Mary Porter, paleontologist Julia Gardner, petroleum geologist Maria Stadnichenko, glacial geomorphologist Ida Ogilvie, Isabel Fothergill Smith, Dorothy Wyckoff, and Anna Heitonen.

Bascom's students went on to become successful scientists and some were featured in ''American Men of Science''. Those featured were Ida Ogilvie, Eleanor Bliss (Knopf), Anna Jonas (Stose), Isabel Smith, and Julia Gardner.

Death

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