Ellen Dorrit Hoffleit (March 12, – April 9, )[1] was an American senior research astronomer at Yale University.

She is best known for her work in variable stars, astrometry, spectroscopy, meteors, and the Bright Star Catalog. She is also known for her mentorship of many young women and generations of astronomers.[2]

Life

Hoffleit's interest in astronomy began with the Perseid meteor shower that she saw with her mother.[3] In , she graduated cum laude with a B.A.

in mathematics.

    • She then went on to work for the Harvard College Observatory, searching for variable stars.[4] In , she was awarded a Ph.D. in astronomy from Radcliffe College[5] and was subsequently hired, in , as an astronomer at Harvard University. She remained at Harvard until when she moved to Yale University.

    She remained at Yale until retirement in [6]

    At Yale she followed in the footsteps of Ida Barney, taking over her astrometric work, and of whom she later wrote "To know [her] was a pleasure, inspiration, and privilege, both at work and socially."[7] Hoffleit also served as director of the Maria Mitchell Observatory on Nantucket Island from to , where she ran summer programs (May–October) for more than students, many of whom went on to successful careers in astronomy.[2] In her final years at Yale, Hoffleit taught basic courses in astronomy to undergraduates.

    Her passionate lectures in Davies Hall, usually with over students, inspired and awed them.[citation needed] She engendered a lifelong interest in astronomy for young women and men, many of whom were just satisfying a prerequisite to their undergraduate degrees.

    During the mid s, Hoffleit consulted for the U.S.

    Army's Ballistic Research Laboratories in "Doppler reductions".[8]

    She was the main editor of the Yale Bright Star Catalogue. The Catalogue is a compendium of information on the 9, brightest stars in the sky. She also co-authored The General Catalogue of Trigonometric Stellar Parallaxes, containing precise distance measurements to 8, stars, information critical to understanding the kinematics of the Milky Way galaxy and the evolution of the solar neighborhood.

    With Harlan J. Smith, Hoffleit discovered the optical variability of the first-discovered quasar3C [9]

    In , Hoffleit was awarded the George Van Biesbroeck Prize by the American Astronomical Society for a lifetime of service to astronomy.

    On March , , Yale University hosted a symposium in honor of Hoffleit's 90th birthday, dedicated to her nearly year career.[10]
