In the late 19th century, Harvard College Observatory was one of the world's top observatories. This was due to the vision, commitment and organizing skills of its director Edward Pickering. But his vision was realized through the hard work and dedication of a team of women assistants sometimes dismissively called Pickering's harem. One of the women was Williamina (Mina) Fleming, who began as a housekeeper and ended her career as an astronomer of international repute.

Williamina Paton Stevens was born in Dundee, Scotland on May 15, 1857. Here is more about the life of Williamina Fleming.
