Edwin Hubble is world famous for his discoveries. Henrietta Swan Leavitt is not. Henrietta was on a team that found a way to measure and classify the universe. They were employed as "human computers" (before the machines existed). Dava's book "The Glass Universe" refers to the half million glass slides Henrietta and other women used to document both the northern and southern skies. An inspiring story of collaboration and discovery.
