The world's first computer programmer, Kay was born in a tiny village, Creeslough - a Gaeltacht region in County Donegal in the civil parish of Clondahorky. 

Kay was born as the War of Independence broke out and her father (James McNulty) was arrested for IRA membership on the night she was born, he spent two years in prison. On his release the family left for Pennsylvania eventually settling in the Chestnut Hill section of Philadelphia. 

Kay excelled at school, particularly in Mathematics and earned a scholarship to attend Chestnut Hill College. Graduating in 1942 she was one of only three women in a class of 100!

After graduation her first job was for the US government, she was hired as a 'computer' calculating missile trajectories during the second world war. She was selected with five other women to work at Aberdeen military base in Maryland, developing the process for a machine called the Electronic Numerical Integrator and Computer (ENIAC). This machine was the world's first electronic general-purpose computer and a huge step forward in technology. Pictured below is Kay handing a print out of ENIAC results to it's inventors Pres Eckert (left) and John Mauchly (right) in a newsreel from 1946.

Kay married Joh Mauchly in February 1948 and subsequently left paid employment, it was unusual in that Mauchly was neither Irish or Catholic and was a widow with 2 children. It is said on their honeymoon he presented her with a cookbook saying 'You are our new cook'. Kay went on to have 5 children of her own while she continued to programme Mauchly new computers in the background. Following Mauchly death in 1980, she continued on the legacy of their software businesses by authoring articles, giving talks and lectures.
