Sister Mary Kenneth Keller
Sister Mary Kenneth Keller was the first woman to earn a doctorate in Computer Science in the United States. Following the completion of her doctoral work in 1965, Keller established the computer science program at Clarke College (now Clarke University), a Catholic women’s college established in Dubuque, Iowa, by the Sisters of Charity of the Blessed Virgin Mary.
