Ruth Hubbard

Ruth Hubbard (March 3, 1924 – September 1, 2016) was a professor of biology at Harvard University, where she was the first woman to hold a tenured professorship position in biology.

During her active research career from the 1940s to the 1960s, she made important contributions to the understanding of the biochemistry and photochemistry of vision in vertebrates and invertebrates. In 1967, she and George Wald shared the Paul Karrer Gold Medal for their work in this area.

In the late 1960s, her interests shifted from science to societal issues and activism. Provided by Wikipedia
