Miss Bonnett and Georgina Myra Richards (née Cumberledge) began work at the Observatory in 1929 and 1930 respectively. As ‘lady computers’, they had to make routine calculations on the observations made by the astronomers. Miss Bonnett left in 1932 but Georgina Cumberledge stayed on, though she transferred to clerical work, the most common form of employment for women at the Observatory after 1936. She married in 1940 and retired from the Observatory. As computers they both worked in the Astrographic Department and are photographed here in the South Building of the Observatory.
Mary Ellen French began work at the Observatory in 1930 as a computer, alongside four other ‘lady computers’ as they were termed. As a computer she had to make routine calculations on the observations made by the astronomers. After several years at the Observatory, she transferred to clerical work. She married in 1939 but remained at the Observatory until 1943. In her time at the Observatory she worked under two Astronomers Royal, Frank Dyson and Harold Spencer Jones. She is photographed here using a solar micrometer to measure the exact position of sunspots on a glass plate of the Sun produced by the astronomers.
