The Glass Universe, by Dava Sobel
An absorbing history of women in astronomy and stellar photography, for readers of Hidden Figures. I enjoyed reading about the women computers and astronomers who worked at the Harvard College Observatory from 1877 through the 1930s, examining glass photographic plates of stars, and analyzing the data, working at half the pay of men. The observatory has a library of these photographs going back more than a hundred years, which is being digitized. These photographs led to several advances in astronomy, as did photographs of stellar spectra. Annie Draper, wanting to see her late husband’s work continue, funded much of the observatory’s work for years. Edward Pickering was the director for many years, followed by Harlow Shapley, and they oversaw new telescopes, expansion of the buildings, grants for women doing graduate work in astronomy, and new mountain observatories in Peru and South Africa. Sobel, known for her witty books on the history of science, such as Longitude, used information found in letters, memoirs, diaries, and notes of astronomy conferences to bring the women, including Annie Jump Cannon and Cecilia Payne, vividly to life.
