Anna Winlock(born September 15, 1857 in Cambridge, Massachusetts; died 1904)) was an American astronomer and daughter of Joseph Winlock. Like her father she was a computer and astronomer. It is plausible that this connection allowed her to be among the first of the women to be known as "the Harvard Computers." She was also a distinguished woman computer as she made the most complete catalogue of stars near the north and south poles of her era. She is also remembered for her calculations and studies of asteroids. In particular she did calculations on 433 Eros and 475 Ocllo.
