Bruno Bertotti (born 1930) is an Italian physicist, emeritus professor at the University of Pavia. He was one of the last students of Erwin Schrödinger. Bruno Bertotti is well known for his contributions to general relativity — particularly the Bertotti-Robinson electrovacuum, an exact solution of the Einstein field equation. He has also obtained a more accurate measurement of the parameter gamma of the parameterized post-Newtonian formalism, with the Cassini radioscience experiment.[1] The PPN gamma parameter measures the curvature of space in metric theories of gravity and it is equal to one in general relativity.[2]

Bertotti was a visiting scholar at the Institute for Advanced Study in 1958-59.[3] In 2007 he was awarded the Italian Gold Medal of Merit in Science and Culture.[4]
