Easter Ellen Cupp (March 30, 1904 – August 27, 1999) was the first woman to get a Ph.D. in oceanography from
Scripps Institution of Oceanography. She is known for her work on diatoms.
Education and career
Cupp was born on March 30, 1904, which was the day Easter holiday is celebrated,[1] in Neola, Iowa.[2]
In 1910 she moved to Whittier, California where she would later attend college.[3] Cupp received an undergraduate degree from
Whittier College (1926),[2] and in 1927 she moved to Berkeley[4] where she received a master's degree from the
University of California (1928). From 1929 until 1934 she worked as a research assistant at the Scripps Institution of Oceanography.[2] In 1934 she earned her Ph.D. from Scripps Institution of Oceanography with her research on
diatoms.[5] Oceanography was a new degree at the time, and Cupp was one of only five people with a Ph.D. in oceanography at the time.[6]
Cupp both conducted research at Scripps and taught classes in phytoplankton ecology with
W.E. Allen who had been her graduate advisor.[7] The director of Scripps,
Harald Sverdrup, had positive reviews of Cupp's work, but in 1939 he fired Cupp because he decided her research did not match the research goals of the institution. Sverdrup replaced Cupp with Marston Sargent who had arrived at Scripps a year earlier.[7] In later year's Cupp's status as the first woman to earn a Ph.D. from Scripps was forgotten by some, and
Naomi Oreskes speculated in 2000 that some were uncomfortable with the firing of Cupp.[8]
After Scripps, Cupp worked with the Navy from 1940 until 1943,[3] and then became a teacher at Woodrow Wilson Middle School in
City Heights, California.[9] She retired from teaching in 1967.[3]
Cupp is known for her research on diatoms, and she published a guide to diatoms found in the western United States,[11] and other locations.[12][13] She published works on different diatoms species she encountered in her investigations.[14] Cupp was also known for her illustrations and collaborated with others on works requiring illustrations.[15][16]
