Early life and education

edit

Dietz was born in Brooklyn, New York, the daughter of Nicholas Dietz and Emma Weidt Dietz. Her mother was active in church work; her father was a lawyer.[1] She graduated from Barnard College in 1925,[2] earned a master's degree from Columbia University in 1926, and completed doctoral studies at Bryn Mawr College in 1929.[3] Her older brother Nicholas Dietz Jr. also became a professor of biochemistry.[4]

Career

edit

Dietz held a post-doctoral appointment as a researcher at Harvard University from 1929 to 1934, working with James B. Conant.[5] In 1934 she went to Munich as a postdoctoral fellow, funded by the American Association of University Women (AAUW).[6] From 1935 to 1937 she was a research chemist for Hercules Powder Company in Delaware.[7][8] She taught chemistry at Moravian College from 1938 to 1941, and at Connecticut College from 1941 to 1943.[1] She returned to industrial work as a chemist at General Aniline Company in Pennsylvania from 1943 to 1945.[3]

After World War II, Stecher was a chemistry professor and pre-med adviser[9] at her alma mater, Barnard College, from 1945 to 1971,[10][11][12] and was an adjunct professor at Pace University from 1971 to 1983. In 1955 she received funding from the National Science Foundation (NSF) for research on benzylidenepyruvic acids.[13][14] She received another NSF grant for science education in 1961.[15]
