Eros, the first near-Earth asteroid, was discovered in 1898 in Berlin. Its orbit was determined only after prediscovery images of it were found on three series of Harvard Observatory photographic plates taken between 1893 and 1896. One of the observatory’s keenest “computers” handled the laborious calculations. Her name was Anna Winlock, and she was among the observatory’s first recruits for its team of female astronomers.
