Anthony C. (Tony) Hearn is an adjunct staff member at RAND and at the IDA Center for Computing Sciences. From 1962 until 1964, he was a research associate in physics at Stanford University, returning as an assistant professor in 1965 after a year at the Rutherford Laboratory in England. In 1969, he joined the University of Utah as an associate professor in physics and was made professor in 1971. From 1973 until 1980, he was professor and chairman of the Department of Computer Science. He joined RAND in July 1980, as head of the Information Sciences Department, a position he held until August 1984. He was a resident scholar at RAND from 1990 to 1996.

Hearn is best known for his pioneering work in mathematical software development, particularly the algebraic computation program REDUCE, which is used in over a thousand scientific institutions throughout the world. He was also one of the founders of the CSNET computer network, winner of the Jonathan B. Postel Service Award for 2009. Hearn has published many articles in the symbolic mathematical computation area including several reviews of the field. He has been involved in research and instructional activities at several organizations in Europe, the most recent being the German National Research Center for Information Technology in Bonn and the Konrad Zuse Center in Berlin. He has served on many national committees sponsored by the National Academy of Sciences, the National Science Foundation and Universities Space Research Association, among others.

Hearn received his Ph.D. in theoretical physics from the University of Cambridge
