Ellen Bradbury grew up in Los Alamos, where her father, Edward Wilder, worked on shaped explosive lenses for the Manhattan Project. She later married John P. Bradbury, the son of Norris Bradbury, who took over as director of the Los Alamos National Laboratory after J. Robert Oppenheimer left in September 1945. She became an art historian and worked on Mabel Dodge Luhan’s papers at Yale University and was the director of several art institutions, including New Mexico’s state Museum of Fine Art, and the Recursos de Santa Fe, among others. She has published several books, including one on Georgia O’Keeffe. More recently, Bradbury has been working on the history and legacy of the Manhattan Project.
