English: Photograph of the Harvard Computers (unflatteringly known as "Pickering's Harem"), a group of women who worked under Edward Charles Pickering at the Harvard College Observatory. The photograph was taken on 13 May 1913 in front of Building C, which was then the newest building at the Observatory. The image was discovered in an album which had once belonged to Annie Jump Cannon. Image courtesy of the Harvard-Smithsonian Center for Astrophysics.
