Born 1 Feb 1859; died 10 Mar 1928 at age 69.

Lydia Maria DeWitt (née Adams) was an American experimental #pathologist who investigated the #chemotherapy of #tuberculosis. Prior to 1910 she made studies in microscopic #anatomy. The remainder of her career she worked in #pathology, #bacteriology and #chemotherapeutics. She searched for dyes that would penetrate tuberculous lesions, and especially with dyes modified by the incorporation of metal atoms such as copper, gold, and mercury. These were tested in animal studies for their potential as an anti-tuberculosis drug. She also conducted influential investigations on the anatomy of the #NervousSystem and on #publichealth practices. She started the #Women'sResearchClub at the University of #Michigan to encourage research by women, and served as its president for several years.
