Sidney Lawrence DuPont

WATERVILLE and ROME – On Labor Day, Sept. 1, 2025, Sidney Lawrence DuPont took the day off and expired at Maine General Hospital in Augusta with his wife and family beside him. Sidney was stricken in his sleep at his camp by a blood clot to his heart.

Sid was born in Bath, on March 30, 1943, to parents Lawrence J. DuPont and Eleanor Cunningham DuPont. He was raised in Farmingdale, and graduated from Gardiner High School in 1961 – the last class to do so. He was a graduate of Higgins Classical Institute in Charleston, in 1962. An avid sportsman and marksman, trained by his beloved grandfather Peter DuPont, Sid was allowed to bring along his deer rifle and hunt in his free time. Next came two years at Wentworth Institute of Technology in Boston, where he excelled in the study of Electrical Engineering.

On July 1, 1965, Sidney became a member of IBEW Local 1253 and began a happy career lasting 55 years. Sid enjoyed “working with the tools” and supporting his fellow Union brothers and sisters. Together they electrified most of the paper mills in Maine, and an atomic nuclear power plant as well.

After a year’s courtship, Sid married Julie Letourneau on June 17, 1967, and together they gave birth to two wonderful sons, Andrew Lawrence of Litchfield, and Joseph Sidney of Waterville. Sidney was a man of few words, but he always put his wife and sons first and knew how to sacrifice to provide them with the best education and a warm loving home. Sid was Julie’s spark for 58 years! He was enormously generous to all.

Sidney enjoyed birdwatching and feeding birds, fishing and hunting, puzzles and making music. He had a knack for remembering lyrics and names of actors. He was also adamant about checking the weather report every day. On occasion, Sid enjoyed a glass of 12-year-old (or older) Scotch – sans ice.

Along with his parents, Sidney was predeceased by his brother, John and his wife Mary Jane; his mother and father-in-law, Lucille and Eugene Letourneau; his brother-in-law, Cyril A. Codere; several aunts, uncles; and cousins.

Besides his wife Julie and two sons, Andrew (and wife Roberta) and Joseph, Mr. DuPont is survived by his sister-in-law, Jeanne Anne Codere, brother-in-law, J. Alfred Letourneau and sister-in law, Lorry; nieces Patty DuPont Kepple (Joseph) and their children Katrina and Joseph; Danielle L. Kane and daughter Katherine; Christina C. Plumer (James) and their son Abram; Julie L. Ayers (Andrew) and their children Emme and Conrad; nephews John DuPont (Stephanie) and children Sarah, Lauren and Logan; William DuPont, Scott Letourneau (Karen); James Letourneau (Jade) and children Daniel and Lydia; Ben Codere (Gabrielle Russell) and their son Lux. Sid was close to his cousins “the Marquis Boys” Roland “Cookie”, Keith, Lynn, and Shawn and Jim DuPont of Brunswick. The best joy was provided by Sidney’s grandchildren and great-grandsons, Aimee DuPont and fiancé Dylan Emery and son Preston; Maya DuPont of Portland; Riley Barth and wife Kayleigh and son Atlas Patrick; Tennyson Martin and partner Kevin Campbell; Noah Barth DuPont and fiancé Shelby Ames. Life was enriched by special friends Rita Pooler, Polly Armstrong, Patty Vashon, Mary Logan, “the two Marks” Ouellette and Letourneau, Aaron Blethen, Paul Estey, Harry Lyons, William Allen and many more faithful friends and extended family members.

Mr. DuPont took his responsibility seriously as a godfather, and prayed for Julie Letourneau Ayers, Stacy Bissonnette Pollard, Kate Pooler, Spencer Violette and Dylan Emery. They will always have a friend looking over them.

The family thanks Rev. Father Tonio Pastin for administering the Last Sacrament to Sidney and praying with us at a very difficult hour.

As per his request, an interment service for Mr. DuPont will be held at St Francis Catholic Cemetery, 78 Grove St., Waterville, on Oct. 4, at 11 a.m.

Arrangements are under the direction of Gallant Funeral Home, 10 Elm St., Waterville.
