He was born on Dec. 27, 1935, in Norwood, Mass., the second son of the late Calvin Jr., and Marion Prince Hosmer. He grew up in Sharon, Mass., attending Sharon schools before finishing high school at Chauncy Hall School in Boston, after his family had moved to York, Maine.
He attended the University of Maine in Orono, graduating in June 1958 with a degree in mechanical engineering. He was commissioned a 2nd Lieutenant in the U.S. Army Reserve through the ROTC program at the university, and reported for a two-year tour of active duty at Fort Knox, Ky., in the fall. After completing his training at Fort Knox, he was sent to Korea, but was medically evacuated after six months due to illness. He finished his tour of active duty back at Fort Knox in the fall of 1960.
He went to work for Sprague Electric Company in Concord, N.H., in 1960, where he designed a variety of machines used for the manufacture of solid tantalum capacitors, which were in high demand in the computer industry.
Five years later he accepted a position with the consulting firm Arthur D. Little in Cambridge, Mass., making his home in Concord, Mass. He worked on machines and equipment for refrigeration at extremely low temperatures and the production of liquefied gases (Cryogenic engineering).

This work resulted in the awarding of 14 patents. He retired in 2004.

Over the years he helped several dozen aspiring engineers to complete their education and find good jobs. He was also a dedicated supporter of his alma mater, serving on the university president's select committee of advisers, endowing a mechanical engineering laboratory there, and giving annual talks on his experiences to freshman and senior engineering students. His services were recognized when he was presented with the university's prestigious Black Bear Award.
