George Stanwood Gordon, Jr., 90, of Concord, Massachusetts, passed away peacefully with family by his side on Thursday, August 28, 2025 following a period of declining health.

George was born in Lynn, MA on January 8, 1935 to his late parents, George Stanwood Gordon, Sr. and Alma Langille Gordon. He was a 1953 graduate of Brooks School, North Andover, MA. He graduated from the Massachusetts Institute of Technology (MIT) in 1957 with a BS (Physics), from Columbia University in 1959 with an MA (Physics), and from MIT in 1962 with a PhD (Physics, Cosmic Rays).

George was active in MIT's ROTC program and served in the U.S. Army Chemical Corps at Fort McClellan in Anniston, Alabama 1962-1963, followed by six years in the U.S. Army Reserves.

George was married to Clarice (nee Barrett) Gordon of St. Paul, Minnesota for over 65 years. They raised five children in Lexington, MA and later retired to Arlington, MA and Concord, MA. He loved spending time at their summer cottage at Lake Sunapee, New Hampshire with his family and friends.

Following military service, George did post-doctoral work at MIT, and then worked at Lincoln Laboratory (Hanscom Field AFB) 1964-1976. He was on the research staff of the MIT Center for Space Research from 1977 until he retired in 1996. He worked on the MIT Plasma Scientific Investigation of the Voyager Project. Voyager I and Voyager II launched in 1977, gathered data during planetary encounters, and Voyager I is still transmitting data from interstellar space. George's skills were integral to downloading and distributing data that Voyager transmitted back to Earth, and he continued to assist with data retrieval into his retirement.

George loved to be out in nature, and spent many hours walking in the woods, birding, and after retirement took up whitewater kayaking both on New England rivers and on many trips to Chile. He travelled extensively with his parents and with his wife Clare, particularly after retirement, including a four-month cruise of southeast Asia, the Indian Ocean islands and Africa for their 50th Wedding Anniversary. George had many interests and kept reading and taking courses life-long. He loved sailing and canoeing, was a ham radio operator, held a private pilot's license, was an enthusiastic photographer of his travels and played classical guitar. George enjoyed home gardening, with a particular love of blueberries. George was an active member of University Lutheran Church, in Cambridge, MA from 1963 until his death. He had a deep faith, and enjoyed Bible Study groups and learning about other faiths. He was a kind and generous person, believing that God loves everyone equally and that we are caretakers of each other and our planet.

George was predeceased by his parents, George S. Gordon, Sr. and Alma Langille Gordon, his sister Alta Berridge and husband Frank, brothers-in-law Orville Caswell, Joseph Bournique and Philip Barrett, sister-in-law Karen Barrett, and daughter-in-law Elizabeth Gordon.
