The true story of 19th century astronomer Henrietta Leavitt plays out against a landscape of fierce sisterly love, early feminism, universe-revealing science, and a time when humans were called “computers.” This beautiful play from Lauren Gunderson (author of Know’s Toil and Trouble and Cincinnati Playhouse’s The Revolutionists) reveals how a group of extraordinary women found a way to measure the universe, providing a glimpse of the light within us all.
