 In the 1950s Bradbury oversaw the development of thermonuclear weapons , although a falling out with Edward Teller over the priority given to their development led to the creation of a rival nuclear weapons laboratory , the Lawrence Livermore Laboratory . In later years , he branched out , constructing the Los Alamos Meson Physics Facility to develop the laboratory 's role in nuclear science , and during the Space Race of the 1960s , the laboratory developed the Nuclear Engine for Rocket Vehicle Application ( NERVA ) . The Bradbury Science Museum is named in his honor .
