Longtime Belfast businessman James Marshal Wentworth, 85, passed away Monday, Oct. 29, 2018, at his home in Belfast overlooking Penobscot Bay.

Born in 1933, Jim was the youngest son of L.L. and Zenaide Wentworth of Knox. Jim graduated from Morse High School in 1951 and continued his education at the University of Maine at Orono. He graduated in 1955 with a degree in electrical engineering and wanting to see the world, went to work for the federal Rural Electrification Administration in Washington, D.C. He was assigned to the southwest where he was involved in expanding and improving electrical services to rural communities in West Texas, New Mexico and Arizona.

While in Abilene Texas, he met newspaper journalist Janet Sue Moore and they were married in 1960. They settled in Lubbock, Texas, where Jim was a partner in Colwell, Wentworth & Associates designing electrical utility projects throughout the southwest. Both daughters, Susan and Julie, were born in Lubbock.

In 1968, Jim had the opportunity start his own design and contracting company and the family relocated to Belfast, where he established WenRock, Inc. electrical contracting and James M. Wentworth P.E., Consulting Engineer. He spent over 40 years working as an electrical engineer and electrical contractor in Midcoast Maine. His work ranged from designing power installations for island electrical co-ops to performing the electrical contracting work for the MBNA complexes in Belfast and Camden. Jim and Janet purchased a house in Casa Grande, Ariz., in 2000 and eventually fully retired, spending summers in Maine and winters in Arizona.

Jim was involved with his community by serving on the Belfast Planning Board, MSAD 34 school board and Waldo County Vocational school board. He was a member of the National Society of Professional Engineers, and held engineering licenses in Maine, Arizona, Texas and Vermont. He was a longtime member of Northport Golf Club.

Jim was preceded in death by his wife of 55 years, Janet Sue Moore Wentworth, in 2015.

He is survived by daughters Susan Simonson of Allentown, Pa., and Julie Wentworth of Corrales, N.M.; granddaughters Kate and Lila Armijo of Corrales, N.M.; grandsons Andrew Simonson of Mebane, N.C., and Brendan Simonson of New York City; and sons-in-law Patrick Simonson and Michael Armijo.
