ABSTRACT
Ruth Hubbard (1924–2016) is known for her groundbreaking research on the biochemistry and photochemistry of the eye and for her social activism. In 1974, she was the first woman to be tenured in biology at Harvard. In addition to her groundbreaking scientific achievements, Hubbard was motivated and influenced by the Vietnam War and the feminist movement, and began to turn her attention to social and political issues. She became an outspoken opponent of any notion of the biological inferiority of women, and also worked to promote the socially and politically responsible practice of science. This article explores Hubbard’s scientific and civic work.
