Dorrit Hoffleit

Ellen Dorrit Hoffleit (March 12, 1907 – April 9, 2007)^[1] was an American senior research astronomer at Yale University.

Hoffleit was born in Florence, Alabama and earned her Ph.D. in astronomy from Radcliffe College in 1938. Starting as a research assistant at the Harvard College Observatory in 1929, she was hired as an astronomer at Harvard in 1948. She remained there until moving to Yale in 1956, staying until her 1975 retirement.^[2]

She was the author of the Bright Star Catalogue, a compendium of information on the 9,110 brightest stars in the sky; she also co-authored The General Catalogue of Trigonometric Stellar Parallaxes, containing precise distance measurements to 8,112 stars, information critical to understanding the kinematics of the Milky Way galaxy and the evolution of the solar neighborhood. In 1988, Hoffleit was awarded the George Van Biesbroeck Prize by the American Astronomical Society for a lifetime of service to astronomy. She turned 100 on March 12, 2007, and died a month later from complications of cancer.^[3]

With Harlan J. Smith, Hoffleit discovered the optical variability of the first-discovered quasar 3C 273.^[4]

Hoffleit was for some time director of the Maria Mitchell Observatory on Nantucket Island as described in her autobiography.^[5]
