Philip S. Abrams is a computer science researcher who co-authored the first implementation of the programming language APL.^[1]

APL

In 1962, Kenneth E. Iverson published his book A Programming Language, describing a mathematical notation for describing array operations in mathematics.^[2] In 1965, Abrams and Lawrence M. Breed produced a compiler that translated expressions in Iverson's APL notation into IBM 7090 machine code.^[1] In the 1970s, he was vice president of development for Scientific Time Sharing Corporation (STSC), Inc.^[3]
