In the winter of 1944, a counterintelligence officer caught Lerner attempting to photograph the [[cyclotron]] at the [[University of California at Berkeley]] Radiation Laboratory, which was part of the [[Manhattan Project]]. The cyclotron had been used in the creation of [[plutonium]] and Lerner was acting without authorization. Lerner resigned and went to work for [[Keynote Recordings]], owned by [[Eric Bernay]], another Soviet intelligence contact. Arthur Adams also worked at Keynote. | In the winter of 1944, a counterintelligence officer caught Lerner attempting to photograph the [[cyclotron]] at the [[University of California at Berkeley]] Radiation Laboratory, which was part of the [[Manhattan Project]].
