Florence Siebert (
October 6, 1897— August 23, 1991) was an American scientistknown for isolating a pure form of tuberculinused in the standard TB test. She is a member of the U.S. National Women's Hall of Fame.
Early life and education
Easton, Pennsylvania, Siebert is said to have read biographiesof famous scientists as a teenager which inspired her interest in science. As a child she contracted poliowhich left her walking with a limp, though the disabilitydid not interfere with her life or work.
Siebert did her undergraduate work at
Goucher Collegeand earned her Ph.D.in biochemistryfrom Yale University. At Yale she studied the intravenousinjection of milk proteinsunder the direction of Lafayette Mendel. She developed a method to prevent these proteins from being contaminated with bacteria.
Professional achievements and awards
In 1923 Siebert worked as a postdoctoral fellow at the
University of Chicago. She was financed by the Porter Fellowship of the American Philosophical Society, an award that was competitive for both menand women.
Siebert served as an instructor in
pathologyfrom 1924-28 at the University of Chicago and was hired as an assistant professorin biochemistry in 1928. At the University of Chicaco she developed a method for purifying the crystalline tuberculin derivative under the supervision of Esmond R. Long. This purified protein derivative (PPD) was used in the standard TB test. The previous tuberculin derivative, Koch's substance, had produced false negative results in tuberculosis tests since the 1890's because of impurities in the material.
In 1932, she became assistant professor in biochemistry at the
University of Pennsylvaniaat the Henry Phipps Institute and rose through the ranks to full professor and professor emeritus in 1959, when she retired. After her retirement she did volunteer work for many years in cancerresearch. Siebert received the Trudeau Medal from the National Tuberculosis Association in 1938, the Garvan Medal from the American Chemical Societyin 1942, and an induction to the National Women's Hall of Fame in 1990.
