Robert F. Simmons
Robert F. Simmons brought psychology and computation together in early natural-language research. He earned a USC psychology PhD in 1954 and worked at RAND and System Development Corporation, where he led language-processing research. His work included Synthex, question answering and access to text and databases. He joined UT Austin in 1968 and studied semantic networks for understanding and generating language. Later work used logic programming. Simmons became an AAAI Fellow in 1992. He retired and died in 1994.

1954–1957
From psychology to computing
Simmons received a psychology PhD at the University of Southern California in 1954. Simmons worked at RAND from 1955 and at System Development Corporation from 1957. He later led the latter’s Language Processing Research Program.

Research before 1968
Question answering and Synthex
At System Development Corporation, Simmons researched natural-language access to databases and text. His work on Synthex sought to synthesize human language behavior through computation. These projects contributed to early computer question-answering research and its language-processing methods.

1968–1980s
Semantic networks and language
Simmons joined UT Austin in 1968 as a professor of computer science and psychology. With students, he developed language-understanding and generation systems using semantic networks. Simmons later worked on logic programming and published the 1984 book Computations from the English.
