      ANS names 2027 Congressional Fellows

      Loumis

      Lockhart

      The American Nuclear Society is excited to announce that it has officially selected two of its members to serve as the 2027 Glenn T. Seaborg Congressional Science and Engineering Fellows. Madeline Lockhart and Aristidis Loumis will provide key support to one of the Society’s four strategic pillars of action: informing policymakers to enable better decisions and stronger policies. They will achieve this by serving a one-year term on Capitol Hill either in a congressional member’s personal office or with a congressional committee, starting next January.

      Some context: ANS Congressional Fellows are among the nearly 30 scientists and engineers who participate annually in the American Association for the Advancement of Science (AAAS) Congressional Science and Engineering Fellowship Program. More than 2,000 fellows have served through the overarching program since its inception in 1973. ANS initiated its program in 2000, and in 2023, expanded it to host two fellows per year.

John W. Simpson (1914-2007)

ANS President 1973-1974

John W. Simpson was elected the 19th president of the American Nuclear Society (ANS). Simpson was a charter member of the Society and elevated to Fellow of ANS in 1958.

John Simpson was born on September 25, 1914. He was top executive and engineer for the Westinghouse Electric Corporation who played a major role in developing the nation’s first commercial nuclear power plant and its first nuclear-powered submarine, the U.S.S. Nautilus.

John joined the Marines in 1933. Just as he was completing basic training, his application to attend the United States Naval Academy was accepted. He graduated from Annapolis in 1937. But in his last year at the academy, he developed near-sightedness and was denied a commission. Instead, he went to work as a junior engineer at the Westinghouse switchboard division in East Pittsburgh, Pa. There he met Rickover, the Navy’s contract officer on the switchboard project. At the same time, he pursued a master’s degree in electrical engineering at the University of Pittsburgh. He received the degree in 1941.

In 1946, he took a two-year leave of absence to work at Oak Ridge National Laboratory. There, with Rickover and a group of engineers and scientists, he helped draft plans for the first attempt at applying nuclear energy to the generation of electricity. He returned to Westinghouse in 1949 and was named assistant manager of engineering at the Bettis Atomic Power Laboratory in Pittsburgh. There, in addition to working on the Nautilus with Rickover, he helped design propulsion plants for the U.S.S. Long Beach and the U.S.S. Enterprise, the nation’s first nuclear surface ships, and for the U.S.S. George Washington, the first nuclear submarine that carried Polaris missiles.

In 1951, Westinghouse received a contract from the federal Atomic Energy Commission to build the first atomic electricity-generating plant, at Shippingport, Pa., and John became manager of the project. In the late 1950s, he organized the company’s astro-nuclear laboratory, which won the federal government’s first contract to develop a nuclear reactor for rocket propulsion. It was successfully tested, but funding was later diverted for other activities.

John was president of the Westinghouse Electric Power Systems Company from 1969 to 1977. He was awarded the Edison Medal of the Institute of Electrical and Electronics Engineers in 1971 for his contributions to electricity generation and naval and space propulsion. His citation reads: “The extent to which he influenced the transition from scientific discovery to practical application in all three areas is to a substantial degree responsible for the eminence of the United States in the atomic energy field today.”

John W. Simpson passed away on January 4, 2007.
