Mary Letitia Caldwell (December 18, 1890 – July 1, 1972) was an American chemist. Most of her work centered on amylase, a starch enzyme, most notably finding a method for purifying crystalline porcine pancreatic amylase.
Early life and education
Caldwell was born in Bogota, Colombia, to American missionaries. She earned her bachelor's degree from the Western College for Women in 1913 and taught at the school until 1918. She earned her M.A. and Ph.D. from Columbia University in 1919 and 1921.
Caldwell spent the rest of her career teaching at Columbia. She became the only female member of the senior faculty in the chemistry department, becoming the first woman to attain the rank of assistant professor at Columbia. She attained the rank of full professor in 1948.
Caldwell had a progressive muscular disability, and was confined to a wheelchair by 1960. Despite this, her 9th floor office at her research facility, Chandler Hall, never changed.
