The American biochemist Mildred Cohn (1913 - 2009) was a trailblazer for women in science, a tireless researcher whose investigations of enzymatic processes and chemical isotopes extended the boundaries of human knowledge. Born to immigrant parents in New York City, she graduated from Hunter College, and earned her doctorate at Columbia University, mentored by Dr. Harold C. Urey. She spent much of her career at the University of Pennsylvania, where she was Benjamin Rush Professor of Biochemistry and Biophysics, conducting much of her work at the Institute of Cancer Research. Among the first women elected to the National Academy of Sciences, she later became President of the American Society of Biological Chemists. Throughout her career, she found excitement in scientific work, joy in penetrating the mysteries of nature. When she was honored by the International Association for Women Biochemists in 1979, she affirmed her hope that more women would participate in this joy, and experience her own zest for science and the satisfaction derived from scientific discussions with dedicated colleagues. She was awarded the American Chemical Society's Garvan Medal, the Franklin Institute's Cresson Medal, and the 1983 National Medal of Science, the highest honor America bestows upon its scientific pioneers. In this audio podcast, recorded at the Academy of Achievement's 1984 Summit in Minneapolis, Minnesota, she shares her love of science with the Academy's student delegates, and recalls her own path to success, as well as the obstacles she had to overcome as a woman in a field dominated by men.
