Maurice Goldhaber (b. April 18, 1911, Lemberg, Austria-Hungary–d. May 11, 2011, East Setauket, NY) studied physics at University of Berlin and received his PhD from Cambridge University. In 1934, Goldhaber and James Chadwick established that the neutron has a great enough mass over the proton to decay while working at the Cavendish Laboratory in Cambridge, England. Goldhaber moved to the University of Illinois in 1938 and published research about beta participles with his wife, Gertrude Scharff-Goldhaber. In 1950, he joined Brookhaven National Laboratory and was director from 1961 to 1973. His brother, Gerson Goldhaber, son, Alfred Scharff Goldhaber, and grandson, David Goldhaber-Gordon, are all physics professors.
