Happy birthday to trailblazing American computer scientist Frances Elizabeth Allen (1932 – 2020) who made foundational contributions to optimizing compilers, optimizing programs and parallel computing. She was the first woman to become an IBM Fellow, where she worked from 1957 to 2002 and as an emeritus fellow afterwards. She was the first woman to win the Turing Prize.

IBM Research was recruiting teachers to teach FORTRAN (1st high-level programming language) to new employees. Needing to pay off student loans & having taken some basic computing courses, she took the job, teaching FORTRAN while learning it herself. She had intended to return to teaching high school but instead stayed with IBM for 45 years. In 1959 she was assigned to the Harvest project for code breaking for the NSA & worked on the Alpha computer language. 🧵2/

She managed the compiler-optimization teams for Harvest and Stretch, IBM’s first transitorised supercomputer. In ‘62 she moved from the IBM facility in Poughkeepsie to Yorkton Heights, where she worked on further supercomputer (ACS-1) and language projects (PL/I). She collaborated with John Cocke on a series of fundamental papers about compiler optimization to improve how higher level languages are translated to machine code.

crucial 1971 paper, ‘A Catalogue of Optimizing Transformations’. Their work introduced the concept of using such graph-theoretical structures to encode a program content in order to efficiently and automatically understand how its parts function together and find ways to optimize code.
In 2006, she won the Associating of Computing Machinery Alan Turing Award, for contributions “of lasting and major technical importance to the computer field” in recognition of her work with supercomputers. 🧵4

She was the first woman to win the prestigious award in its 40 year history.
In 2022, the IEEE presented the IEEE Frances E. Allen Medal for the first time for innovative work in computing leading to lasting impact on other fields of engineering, technology, or science. 🧵5/5
