Happy Nunday! Here at A Nun’s Life Ministry we celebrate some Mondays in a special way — Mondays become Nundays when we have photos of Catholic sisters and nuns to share with you.

Today's Nunday photo is Sister Mary Kenneth Keller, BVM. She entered the Sisters of Charity of the Blessed Virgin Mary, of Dubuque, Iowa in 1932.

Sister Mary Kenneth is recognized as one of the first women to receive a Ph.D. in computer science. Her pioneering efforts won her a national reputation in a male dominated field. She established the nation’s first small college computer science program at Clarke University (then Clarke College), authored four books with IBM, and served as consultant on new technology for leaders in education, government, and business.
