Programmers of ENIAC (dedicated 1946) – Several women did large parts of this project: Adele Goldstine, Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman, but most histories of ENIAC have not talked about what they did. Instead, they focus on hardware accomplishments rather than software accomplishments.
