## Bio

Edwin Mattison McMillan graduated from Caltech and earned his doctorate from Princeton in 1933, then joined Berkeley's Radiation Laboratory where he discovered oxygen-15 and beryllium-10. In 1940 he produced neptunium, the first transuranium element, work that would earn him half of the 1951 Nobel Prize in Chemistry alongside Glenn Seaborg. World War II pulled him into microwave radar at MIT, sonar development for the Navy, and then the Manhattan Project in 1942, where he helped establish Los Alamos and led teams on the gun-type bomb design while contributing to the implosion weapon. After the war he co-invented the synchrotron with Vladimir Veksler and returned to Berkeley to build them. He rose to associate director in 1954, deputy director in 1958, and became director when Ernest Lawrence died later that year, holding the post until his retirement in 1973.
