Herb Grosch

Herbert Reuben John Grosch (September 13, 1918 – January 18, 2010) was an early computer scientist, perhaps best known for Grosch's law, which he formulated in 1950. Grosch's Law is an aphorism that states "economy is as the square root of the speed."

Biography

Born September 13, 1918, in Saskatoon, Saskatchewan, Grosch was the first baby to survive incubator Grosch moved to Midland, Ontario as a child, then Pembroke, then Chatham, and later Windsor, Ontario.

Grosch moved to the United States where he received his B.S. and PhD in astronomy from the University of Michigan in 1942. In 1945, he was hired by IBM to do backup calculations for the Manhattan Project working at Watson Scientific Computing Laboratory at Columbia University. According to an IBM history, he had been previously employed as an optical engineer in defense industry and was eager to return to research. In 1951, he went on to work on Project Whirlwind at MIT, and on other early computer projects at General Electric. Back at IBM, he served as their first space program manager in 1958-1959.

Grosch served as editor of the journal Computerworld from 1973 to 1976, and he was the president of the American Rocket Society (which became the American Institute of Aeronautics and Astronautics) and the Association for Computing Machinery from 1976 to 1978.

Grosch received the Association for Computing Machinery Fellows Award in 1995, and the citation that accompanied it read, "A computer pioneer who managed important space and technology projects, Grosch is respected for discovering and describing the relationship between speed and cost of computers."

He was the second scientist hired by IBM (after Wallace J. Eckert) and the first employee at that company with facial hair, at a time when beards were prohibited by IBM.

On Grosch's religious views, he was an atheist.
