He attended St. Mark's School, graduated from Harvard College in 1932 and attended Harvard Graduate School of Business Administration. Adams was a sixth-generation Harvard legacy student (John Adams graduated from Harvard in 1755).

Adams was commissioned as an ensign in the Naval Reserve on 23 June 1932 and was promoted to lieutenant (junior grade) on 23 June 1937. He served on active duty during World War II. Adams was promoted to the rank of lieutenant commander on 1 May 1943 and to commander on 1 March 1944. He took command of the destroyer escort USS William Seiverling when she was commissioned on 1 June 1944.

During his tenure, Raytheon grew from a manufacturer of transistors and vacuum tubes into a maker of missiles and military-oriented radar and communications systems.^[2]

Penati by whom he had one stepson: Giannotto Penati.
