For the first time, we can now mechanically simulate the cognitive process. –Sister Mary Kenneth Keller
Sister Mary Kenneth Keller established herself as a strong influence in the world puter science at a time when women in the field were unheard of. At the same time, her work paved the way for what we now understand as the information economy – a key driver of wealth creation. She was the first woman in the United States to earn a Ph.D. puter science and later went on to help develop the BASIC programming language (Beginners All-Purpose Symbolic Instruction Code), which transformed the world puter science.
Relatively little information is known about Keller’s early life. She was born on December 17, 1913, to John Adam Keller and Catherine Josephine (née Sullivan) in Cleveland, Ohio. In 1932, she followed God’s call to the Sisters of Charity of the Blessed Virgin Mary in Dubuque, Iowa, and in 1940 took her vows with the congregation. She then began her academic career in pleting both a B.S. in math and an M.S. in math and physics from DePaul University in 1943 and 1953, respectively.
In 1958, Keller started at the National Science Foundation workshop in puter science center at Dartmouth College, which was an all-male school at the time. While there she teamed up puter scientists John G. Kemeny and Thomas E. Kurtz to develop the BASIC programming language.
BASIC puter programming by allowing anyone who could learn the language to write custom software. Before BASIC, only mathematicians and scientists could do so. Versions of BASIC became widespread on the first puters in the 1970s and 1980s, allowing everyone from business owners puter hobbyists to develop software.
Throughout her graduate studies Keller was associated with several other prestigious institutions in addition to Dartmouth, including the University of Michigan and Purdue. Keller eventually earned her Ph.D. puter science from the University of Wisconsin– Madison in 1965. Her thesis was titled “Inductive Inference on Computer Generated Patterns.”
Keller went on to establish puter science department at Clarke College, a Catholic college for women founded by the Sisters of Charity of the Blessed Virgin Mary. She chaired the department for 20 years, where she was an advocate for women puter science. She was noted for her support of working mothers and even encouraged mothers to bring their babies to class with them.
Keller was one of the first to recognize and acknowledge the future extensive puters would have in the world. In 1964, she noted that students in fields such as psychology and the sciences were already puters to be useful in their academic work. She advocated for the use puters in education and established a master’s degree program puter applications in education at Clarke. She also predicted the puters would have in libraries, saying, “Its function in information retrieval will make it the hub of tomorrow’s libraries.”
Keller was enthusiastic about providing access puters to everyone, not puter scientists. “We’re having an information explosion, among others”, she said, “and it’s certainly obvious that information is of no use unless it’s available.”
In her honor, Clarke University (formerly Clarke College) has established the Mary Kenneth Keller Computer Science Scholarship and the Keller Computer Center, which puting and munication support to Clarke University staff, faculty members and students. Keller died at the age of 71 in Dubuque, Iowa, on January 10, 1985.
