He was most currently residing at Atria Assisted Living in Fairhaven, Massachusetts with his wife, Bobbie, of 69 years. The first in his family to earn a college degree, Peter was awarded full-ride scholarships to the University of Rochester, where he graduated Phi Beta Kappa in 1952 with a degree in Mechanical Engineering and a master's degree in the same field in 1955. He went on to earn a doctorate in Mechanical Engineering at MIT, in 1960.

It was at the University of Rochester that Peter met the love of his life, Mildred (Bobbie) Edwards, on a blind date arranged by friends. They were married on August 27, 1955.

In his later years Peter enjoyed many years of travel, visits with grandchildren, and contented retirement with his wife. He passed peacefully on January 11, 2025 at the age of 94.
