Anne Walker was a British astronomer and one of the first women employed in paid routine work in astronomy in her country. She was one of a number of women computers employed at Cambridge Observatory between 1876 and 1904. Unlike most of these women, Walker remained at the observatory for a significant period of time. Andrew Graham retired in 1903 at the age of eighty-eight. Anne Walker resigned at the same time as him, bringing her astronomical career at the Cambridge Observatory to an end after 21 years.
