Upon graduation, Dwight joined the Air Force, and after OCS, he was assigned as a second lieutenant at Laon Air Base, near Paris. While in France, he reconnected with Mary Edythe, a Westminster Choir College graduate whom he originally met while they both had summer jobs on Lake George, N.Y. He and Mary were married in 1954 and they settled in White Plains, N.Y., where he took a job as a stockbroker with Kidder Peabody. In 1989, he moved to A.G. Edwards as a stockbroker and financial consultant, where he used his training in mathematics to become a respected expert on stock options.
He and Mary were involved in several suburban activities and rarely missed a Sunday singing in the White Plains Presbyterian Church choir. Predeceased by his wife, Dwight passed away at his White Plains home May 26, 2023. He is survived by two children and two grandchildren.
