John Jacob Abel

Born 19 May 1857; died 26 May 1938 at age 81. American biochemist and pharmacologist who made important contributions to a modern understanding of the ductless, or endocrine, glands. In 1893, he became the first full-time professor of pharmacology in the U.S. at John Hopkins University. Abel encouraged his students to conduct experiments and become active participants in his laboratory research. In 1897 he reported the isolation of a derivative of epinephrine (adrenaline). In 1926, he isolated and crystallized insulin. Abel also investigated the functions of the kidney and devised a vividiffusion apparatus for removing toxins from the blood of living animals, an apparatus that is widely regarded as a forerunner of the artificial kidney.
