In 1965, she became the first woman to earn a Ph.D. in computer science in the U.S. Then she founded a computer science department at a small women's college—and ran it for 20 years, believing computers should serve humanity, not replace it.
Her name was Sister Mary Kenneth Keller, and she was a pioneer in both computer science and education.
EARLY LIFE
Born Evelyn Marie Keller on December 17, 1913 in Cleveland, Ohio, she grew up in an era when few women pursued higher education, much less science.
At age 18, in 1932, Evelyn entered the Sisters of Charity of the Blessed Virgin Mary (BVM), a Catholic religious order dedicated to education.
She took the religious name Sister Mary Kenneth.
THE EDUCATION
Sister Mary Kenneth's order valued education, and she pursued it passionately.
She earned a B.S. in Mathematics from DePaul University in 1943.
She earned an M.S. in Mathematics and Physics from DePaul University in 1953.
But in the late 1950s and early 1960s, a new field was emerging: computer science.
Computers were enormous, expensive machines used primarily for military and scientific calculations. Very few universities even taught computing.
Sister Mary Kenneth was fascinated.
THE BREAKTHROUGH AT DARTMOUTH
In the early 1960s, Sister Mary Kenneth worked at the Dartmouth College computer center—one of the few places in the country with cutting-edge computing facilities.
At the time, Dartmouth was an all-male college. But they made an exception for Sister Mary Kenneth, allowing her access to their computing resources.
She worked on the development of BASIC (Beginner's All-purpose Symbolic Instruction Code)—a programming language designed to be accessible to non-experts.
BASIC would eventually become one of the most widely used programming languages, helping democratize computing.
1965: THE Ph.D.
In 1965, Sister Mary Kenneth Keller received her Ph.D. in Computer Science from the University of Wisconsin-Madison.
She was the first woman in the United States to earn a doctorate in computer science.
(Another student, Irving C. Tang, received his computer science Ph.D. from Wisconsin the same year, making them among the very first computer science Ph.D.s ever awarded.)
Her dissertation: "Inductive Inference on Computer Generated Patterns."
CLARKE COLLEGE: 1965-1985
After earning her doctorate, Sister Mary Kenneth could have worked anywhere—major research universities, tech companies, government labs.
Instead, she went to Clarke College (now Clarke University) in Dubuque, Iowa—a small Catholic liberal arts college for women.
In 1965, she founded Clarke's Computer Science Department—one of the first computer science departments at a women's college in the United States.
This was revolutionary. In 1965:
Computer science was barely recognized as a discipline
Most universities didn't have CS departments
Women were actively discouraged from science and technology
Computing was seen as a "male" field
Sister Mary Kenneth believed women should have access to computing education—and she built a program to make it happen.
THE PHILOSOPHY
Sister Mary Kenneth's approach to computer science was deeply humanistic.
She believed:
Computers should serve humanity, not replace human judgment
Technology should democratize education, making knowledge accessible to everyone
Ethics and social responsibility were as important as technical skill
Women and liberal arts students should have access to computing
She famously said: "We're having an information explosion, and it's going to revolutionize education."
She advocated for computer literacy decades before it became mainstream.
20 YEARS AS CHAIR
Sister Mary Kenneth chaired Clarke's Computer Science Department for 20 years (1965-1985).
She:
Secured grants and funding for equipment
Developed curriculum emphasizing both technical skill and ethical considerations
Mentored generations of women in computer science
Made Clarke a pioneer in computing education at women's colleges
JANUARY 10, 1985
Sister Mary Kenneth Keller died on January 10, 1985 in Dubuque, Iowa at age 71.
She had spent 20 years building Clarke's computer science program, training hundreds of students, and proving that women belonged in computing.
THE LEGACY
Sister Mary Kenneth Keller's impact:
Breaking barriers: First woman to earn a computer science Ph.D. in the U.S.
Expanding access: Founded CS department at women's college when most women were excluded from computing
Humanizing technology: Advocated for ethical, human-centered computing before it was mainstream
Mentoring women: Trained generations of women computer scientists
Democratizing computing: Believed technology should serve humanity and education
Today, women remain underrepresented in computer science (about 20-30% of CS degrees go to women, depending on country and level).
Sister Mary Kenneth's vision—of computing as a tool for human flourishing accessible to everyone, regardless of gender—remains as relevant as ever.
In 1965, she became the first woman to earn a Ph.D. in computer science in the U.S.
Then she founded a computer science department at a small women's college.
She ran it for 20 years, believing computers should serve humanity, not replace it.

Computer scientist. Educator. Pioneer.
She didn't just break into computing—she opened the door for women to follow.
