Leonard Charles Maximon, 94, died on January 4, 2020. Leonard received his AB degree in Physics from Oberlin College in 1947. He was awarded a PhD degree in Theoretical Physics from Cornell University in 1952. In 1951 he was appointed as an assistant professor of applied mathematics at Brown University, a visiting professor at the Physics Institute of the Norwegian Technical University in Trondheim, a fellow at The University of Manchester, England, and then took a position on the staff of the Center for Radiation Research of the now National Institute of Standards and Technology. During that time, he was a visiting scientist and collaborator at the Center for Nuclear Studies in Saclay, France. He joined the National Bureau of Standards in 1958, where he remained for over two decades. In 1980, he started his "second" career in teaching and research at George Washington University. Upon his retirement from George Washington in 2015 he was awarded Emeritus status. Leonard and his wife, Marie-Cecile, enjoyed dividing their time between Surry, Maine; Paris, France; and Scottsdale, Arizona residences. Leonard cared for Marie-Cecile during her illness and remained in Scottsdale following her death in November 2015. Early in his career Leonard had discovered a love of working with youth, and devoted summers and other opportunities to young people, including a summer as a science teacher in the African Science Workshop in Entebbe, Uganda, and later as a consultant with the Head-start Program in greater New York metropolitan area. His gift for working with young people became the basis of his final endeavor when he was a Visiting Professor with the ASU Herberger Young Scholars Academy (HYSA) for gifted students in Phoenix by supporting students in physics, theater, French and math. He taught a number of courses at ASU in Barrett Honors College and was an adjunct professor in the Physics Department at ASU. Leonard is survived by cousins and his step-daughters, Marie-Cecile's children: Sybil Francis, Corinna-Barbara Francis and Gaetane Francis. Leonard’s ashes will be joined with those of his wife and placed in a grave in the National Memorial Cemetery of Arizona in Phoenix. Memorial donations can be made to: ASU Herberger Young Scholars Academy for student-led memorial in Leonard's honor. Other options include: Jewish National Fund and Nature Conservancy .
