BIOGRAPHY: Engineer Wilber Y. Walworth was born on December 17, 1917 in Adrian, Michigan. He grew up in Ann Arbor, Michigan, and attended the University of Michigan, graduating in 1941 with a bachelor’s degree in engineering. His wife, Vivian Walworth, also attended the University of Michigan, earning a degree as a chemist. Following their graduation, they moved to Rochester, New York where Walworth began working for the Ritter Dental Manufacturing Company. After working at Ritter Dental for two years, he joined the Submarine Signal Company in Boston, Massachusetts, where he was appointed a Radar Field Engineer for the U.S. Navy in World War II. He was assigned the rank of Apprentice Seaman and worked to install and maintain the radar equipment on various ships and in shipyards throughout the U.S. Following his service in World War II, Walworth continued working for the Submarine Signal Company through their merger with Raytheon Company in 1946. In mid-1946, he was chosen to serve as a civilian observer in the Electronics Group of “Operation Crossroads,” the two atomic bomb tests at the Bikini Atoll. Throughout the course of the operation, he observed the effects of the bombs on the equipment onboard ships subjected to the test, as well as in the observation fleet. Following his “Operation Crossroads” assignment, Walworth continued working for Raytheon to develop and refine electronics and radar equipment. In 1952, the Walworths moved to Concord, Massachusetts, where they lived in the Conantum neighborhood. Wilber Y. Walworth passed away on April 20, 2001.
