Frances Allen, first woman to win award for contributions to computing, dies at age 88

Frances Allen, a former high school math teacher who became one of the leading computer scientists of her generation and, in 2006, was the first woman to win the A.M. Turing Award, considered the Nobel Prize in computing, died in Schenectady, N.Y., on Aug. 4, her 88th birthday.

Her grandnephew, Ryan McKee, confirmed her death. The cause was complications of Alzheimer’s disease.

Renowned for her seminal work in optimizing the creation of computer software programs and high-performance computing systems, Allen earned her stellar reputation in the esoteric field of software compilers. Simply put, her efforts over a distinguished 45-year career at IBM helped software designers generate more powerful and efficient code, which led to huge advances in the use of supercomputers and parallel processing, and eventually in all levels of computing.

When she began her career in the late 1950s, years before universities began offering computer science degrees, software programmers working on room-size mainframe computers were hampered by having to hand-code programs line by line and spend time figuring out how to adjust slow software to run faster. These tweaks often led to more complexity and bugs in the software. The advent of software compilers allowed for automatic optimization of software, which freed up valuable time for programmers and resulted in more powerful and more useful software.

Allen, after being introduced to the FORTRAN programming language when it was released in 1957, was fascinated with compiler optimization early in her career and became one of the leading visionaries in the field. Because of its compiler program, FORTRAN enabled a manner of communication with the computer that was closer to human understanding. With that as her model, Allen was inspired to make compilers more efficient.

Her work, which set the tone for how people in the field think about compiler optimization, bridged the gap between how computers communicate and how people communicate, thus opening up the use of computers to scientists and engineers and others outside the glass-enclosed fortresses of the data centers.

“Fran Allen’s work has led to remarkable advances in compiler design and machine architecture that are the foundation of modern high-performance computing,” said Ruzena Bajcsy, an emeritus electrical engineering and computer science professor at the University of California at Berkeley and chair of the Association for Computing Machinery’s A.M. Turing Award Committee when Allen won the award in 2006.

“Her contributions have spanned most of the history of computer science and have made possible computing techniques that we rely on today in business and technology,” Bajcsy said.

A fervent mentor for IBM researchers, Allen also was committed throughout her career to fostering women’s interest in computer science. In 1989, she became the first woman to be named an IBM fellow, the highest honor accorded a technical person in the company. She spoke at conferences around the world, urging women to consider careers in science and technology. In honor of her efforts, IBM established the Frances E. Allen Women in Technology Mentoring Award in 2000.
