Maurice Goldhaber (April 18, 1911 – May 11, 2011) was an American physicist, who in 1957 (with Lee Grodzins and Andrew Sunyar) established that neutrinos have negative helicity. Early life and childhood He was born on April 18, 1911, in Lemberg, Austria, now called Lviv, Ukraine to a Jewish family. His son Alfred Goldhaber is a professor at the C. N. Yang Institute for Theoretical Physics at SUNY Stony Brook. His grandson, David Goldhaber-Gordon is a Physics Professor at Stanford University. Education After beginning his physics studies at the University of Berlin, he earned his doctorate at Cambridge University in 1936, belonging to Magdalene College. Career In 1934, working at the Cavendish Laboratory in Cambridge, England he and James Chadwick, through what they called the nuclear photo-electric effect, established that the neutron has a great enough mass over the proton to decay. He moved to the University of Illinois in 1938. In the 1940s with his wife Gertrude Scharff-Goldhaber he established that beta particles are identical to electrons. He joined Brookhaven National Laboratory in 1950. With Edward Teller he proposed that the so-called "giant-dipole nuclear resonance" was due to the neutrons in a nucleus vibrating as a group against the protons as a group (Goldhaber-Teller model). He made a well-known bet with Hartland Snyder in about 1955 that anti-protons could not exist; when he lost the bet, he speculated that the reason anti-matter does not appear to be abundant in the universe is that before the Big Bang, a single particle, the "universon" existed that then decayed into "cosmon" and "anti-cosmon," and that the cosmon subsequently decayed to produce the known cosmos. In the 1950s also he speculated that all fermions such as electrons, protons and neutrons are "doubled," that is that each is associated with a similar heavier particle. He also speculated that in what became known as the Goldhaber-Christie model, the so-called strange particles were composites of just 3 basic particles. He was Director of Brookhaven National Laboratory from 1961 to 1973. Among his many other awards, he won the National Medal of Science in 1983, the Golden Plate Award of the American Academy of Achievement in 1985, the Wolf Prize in 1991, the J. Robert Oppenheimer Memorial Prize in 1982 (shared with Robert Marshak), and the Fermi Award in 1998. He was an elected member of the United States National Academy of Sciences, the American Academy of
