Robert Rae Nicholas, 82, formerly of Byfield, Mass., and Belmont,, died April 5, 2010, at Bellamy Fields Assisted Living Center in Dover, N.H. He was the husband for 44 years of Doris (Jones) Nicholas, who died in 1996.

Born in Richmond, Ind., Feb. 15, 1928, he was a son of George H. and Florence (Williams) Nicholas and was a graduate of Allderdice High School in Pittsburgh, class of 1946.

A veteran of World War II, he served in the Army Military Police, stationed in Japan.

After returning from the war, he continued his education, graduating from the State Teachers College at California in Pennsylvania in 1952.

He had a 30-year career as an engineer with General Electric, retiring in 1989, and remained an active member of the General Electric Retirement Association.

An avid outdoorsman, he especially loved the mountains and the ocean. He was a member of the Appalachian Mountain Club, volunteered at Acadia National Park and the Owls Head Transportation Museum.
