Henrietta was on a team that found a way to measure and classify the universe. They were employed as &quot;human computers&quot; (before the machines existed). Dava's book &quot;The Glass Universe&quot; 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.
