Helen Abbott Michael
Helen Cecilia De Silver Abbott Michael, M.D. (December 23, 1857 – November 29, 1904) was an American scientist who was among the first to "in a systematic way study the relation of chemical composition to species of plants and to plant growth." Michael theorized that the chemical composition of plants over the course of their development provided an illustration for the theory of evolution. She also was a student of Tufts, and later Harvard, organic chemist Arthur Michael (known for the Michael reaction), who she subsequently married.
