The history of women in computing is a story that is only just beginning to be told. There are certain women, like Grace Hopper, who are (deservingly) well-covered in the history, but many of the women who made important contributions are still unknown.
A recent documentary, Top Secret Rosies, by LeAnn Erickson, is currently touring the country. The film tells the story of the female computers who worked on computational projects during the second world war. As of the historical consultants and “talking heads” on the film, I can recommend it highly. There seems to be a burst of coverage on the film everywhere from CNN to Slashdot.
