Robert A. Chalmers ’52

Bob died Dec. 24, 2006, from the effects of Alzheimer’s disease in Rancho Palos Verdes, Calif.

He entered Princeton from Wyomissing (Pa.) High School with strong talents in physics and music. He was an enthusiastic four-year member of the Glee Club, a Bric-a-Brac photographer, and a WPRU producer. He majored in music and roomed senior year in Prospect Club with Hale Bradt and Jim Melchert.

After graduation, Bob served in the Naval Reserve and attended Northwestern University, where he earned a Ph.D. in nuclear physics in 1963. He then worked at Lockheed in nuclear research and artificial intelligence, exploring his love of computers and programming, until his retirement in 1994.

He remained active in music through recorder ensembles and was an avid bicyclist. After the 1993 death of his first wife, Suzanne, he married Lillian Singletary, a physicist he had known since graduate school, who survives him.

Bob is warmly remembered for his good humor, contentment with a modest lifestyle, and playful approach to life. His spirit lives on in his two sons, Doug and Chris, both of whom are in technical fields, and his four grandchildren. His class offers its condolences to his entire family.
