Short description: American computational physicist

Harold Varner McIntosh (1929–2015) was an American computational physicist who worked for many years in Mexico. Beyond physics, his research interests included quantum chemistry, programming language design, cellular automata, and flexagons.[1]

Early life and education

McIntosh was born on March 11, 1929, in Colorado, and was an undergraduate at the Colorado State College of Agriculture and Mechanic Arts (now Colorado State University), where he graduated in 1949 with a degree in physics. He went on to graduate study at Cornell University, earning a master's degree in 1952. He began doctoral study at Brandeis University, but stopped before completing the program.[1][2]

Much later in his career, he completed a doctorate in quantum chemistry at Uppsala University in Sweden in 1972.[1]

Career and later life

After leaving Brandeis, McIntosh worked at the Aberdeen Proving Ground, and then in the Research Institute for Advanced Studies in Baltimore. In 1962 he moved to the University of Florida to work on quantum theory in the department of physics and astronomy there.[1]

In 1964, McIntosh moved to Mexico, where he would work for the rest of his career. He started in the center for research and advanced studies of the Instituto Politécnico Nacional, which eventually became CINVESTAV; he worked there on the design of the CONVERT programming language. After another year as director of programming at the computer center of the National Autonomous University of Mexico (again working on programming language design) he returned in 1966 to the Instituto Politécnico Nacional as a professor in the School of Physics and Mathematics and coordinator for applied mathematics. Here, as well as the development of programming languages and software for scientific visualization, his interests returned to physics, including issues of degeneracy in the solution of physical equations, and quantum two-body problems involving a magnetic monopole (the so-called MICZ Kepler system, in which the M stands for McIntosh).[1]

After nine years at the Instituto Politécnico Nacional, McIntosh moved in 1975 to the Institute of Sciences of the Meritorious Autonomous University of Puebla, where he became the founding director of the Department of Microcomputer Applications. There, his interests shifted to cellular automata for the final decades of his career.[1][2]

He died in Puebla, Mexico on November 30, 2015.[1]

Recognition

McIntosh was a member of the Mexican Academy of Sciences.[3] In 2008, a special issue of the Journal of Cellular Automata was published in his honor.[2]
