Croasdale, Hannah, 1905-1999

Biography

Hanna T Croasdale, was born on Nov. 8, 1905, in Pennsylvania. She graduated from the University of Pennsylvania with a BS in 1928. She received her MS in 1931, and her Ph.D. in 1935. That same year she began work as a research assistant at Dartmouth Medical School. She joined the Dartmouth College zoology department as a technical assistant in 1937. She held that position until 1953, when she was promoted to research associate with the rank of instructor. In 1961, she became an associate professor, but it was another two years before she was allowed to teach classes. After the zoology and botany departments merged in 1963, she was again promoted to associate professor of biology, with tenure. She became a full professor in 1968, three years before she retired from the college. Because she was denied access to instruction at school because of her gender, she was soon recognized for her precise translation of biological taxa. She published extensively and was vice president (1964) and then president (1967) of the Phycological Society of America which she helped to establish. In 1983, the Hanna T. Croasdale Award was established, to be awarded each year to the person who made the most significant contribution to quality of life for women at the College. Dr. Croasdale died on July 27, 1999.
