PEOPLE New director at Cornell... MauryTigner, who two decades ago was the driving force behind the half-mile-circumfer­ ence electron accelerator at Cornell, has been named next director of Cornell's Laboratory of Nuclear Studies (LNS).Tigner will succeed Karl Berkelman, who steps down on 30 June. LNS operates the Cornell Electron Storage Ring. Tigner was professor of physics at Cornell from 1977 to 1994 and in his final year was named the first holder of the Hans A Bethe Pierre-Etienne Bisch (left), Prefet of the Chair in Physics, a post that a serious illness departement de I'Ain, France, with CERN forced him to relinquish.
