Monroe A. Weiant Jr.

Monroe Alden Weiant Jr., age 90, of Bedford, MA, loving husband and father of two children, passed away on Tuesday, October 7, 2025.

Monroe was born in 1935 in Perth Amboy, New Jersey to the late Monroe and Lois Weiant (née Dayer). He earned a bachelor’s degree in electrical engineering from Rutgers University in 1957, during which time he met his beloved wife Katherine. They married in 1958. 

After college, Monroe moved to Arlington, Virginia to serve in the Air Force. He was assigned to the National Security Agency, with a “top secret” security clearance, to work in cryptography. After service, Monroe and Katherine moved to Melbourne, Florida, where Monroe worked at Radiation, Inc. (later renamed Harris Corporation). During this time, he participated in projects to design the telemetry of rockets and earned a master’s degree in electrical engineering from the Florida Institute of Technology. Monroe and Katherine had two dearly loved children, Bruce and Susan, in 1959 and 1963, respectively.

In 1978, Monroe and Katherine moved their family back north to Trumbull, Connecticut. There, Monroe worked for Pitney Bowes, developing cybersecurity for mailing machines. Monroe remained in Trumbull until shortly after Katherine’s death in 2023, when he relocated to Bedford, Massachusetts to be closer to his daughter and caretaker, Susan. 

Monroe was brilliant, kind, and absolutely devoted to his family. He had a genius IQ, which led to diverse interests and a lifelong love of learning – he was a gifted pianist, organist, and tennis player, and a student of art and chess. Despite being a mild-mannered engineer, he had an adventurous spirit and a great sense of humor throughout his life. He unflinchingly killed rattlesnakes in his Florida yard to protect his children. And later in life, he returned to Florida annually with his daughter and granddaughters, spending hours digging in the sand and being run over with an alligator pool float. Monroe was steadfast, patient, and deeply invested in the lives and interests of his loved ones. His daughter Susan fondly remembers practicing duets on the piano, for which they would diligently memorize song lyrics in the car while running errands, and deep, late-night conversations after all others had gone to bed. Even as his health deteriorated due to Parkinson’s Disease, Monroe remained generous and optimistic – he hoped to live to 100, and became close friends with his aides in both assisted living and nursing care. 

Survivors include two loving children, Bruce Weiant and his wife Elaine and Susan Smith and her husband Christopher, two granddaughters, Emily Hamilton and her husband Kyle and Sarah VanKerkhove and her husband Derek, nephew, Erik McGaughey and his wife Deborah, great nephews and great niece, Zachary, Charli and Emily. He was predeceased by his wife Katherine and his brother William.

A private family gathering will be held to celebrate the life of Monroe. In lieu of flowers, the family requests those who wish to express sympathy to consider making a donation to the Parkinson's Foundation, www.parkinson.org in Monroe's name.
