Frances Spence (March 2, 1922 - July 18, 2012) was one of the original programmers for the ENIAC computer.
She was born Frances Bilas in Philadelphia in 1922. She attended Temple University but then was awarded a scholarship to Chestnut Hill College. She majored in mathematics with a minor in physics and graduated in 1942. While there, she met Kathleen McNulty, who also later became an ENIAC programmer. Although one of the original programmers of the ENIAC, her role as well as the other woman contributors were downplayed, due to the stigma that woman didn't like technology. McNulty and Spence were hired by the Moore School of Engineering to compute ballisticstrajectories. Both were selected to become part of the first group of programmers for the ENIAC, which was designed to perform the same calculations. In 1947, she married Homer Spence, an Army electrical engineer from the Aberdeen Proving Grounds who had been assigned to the ENIAC project and later became head of the Computer Research Branch. Shortly after that, she resigned to raise a family.
