Martin M. Block

Martin Moses Block (November 29, 1925 – July 22, 2016) was an American physicist, known as a co-discoverer with Aihud Pevsner of the eta meson in 1961. Pevsner was the leader of the Johns Hopkins University team, and Block was the leader of the Northwestern University team.

Biography

Block was born in Newark, New Jersey. He graduated from Columbia University in 1947 with B.S., in 1948 with M.A., and in 1952 with Ph.D. supervised by William W. Havens Jr. At Columbia, Block helped to design the magnets for the Nevis cyclotron. In 1949 he married Beate Sondheim. He joined the faculty of Duke University in 1951. He attended the University of Rochester's 6th Annual Conference on High Energy Nuclear Physics, where he contributed a paper and roomed with Richard Feynman. Block suggested to Feynman that parity is not conserved in weak interactions, and Feynman raised the question with the other experts. At Duke University, Block led the team that developed the world's first liquid-helium bubble chamber, which was used for study of several newly discovered particles. In 1961 he left Duke University for Northwestern University, where he remained on the faculty until he retired as professor emeritus in 1996. At Northwestern University, he did research on large spectrometer counter and spark chamber systems. In the early 1960s he did research at Giampietro Puppi's lab. At CERN in 1964–1965, as a Ford Foundation Fellow, a NATO Fellow, and a UNESCO Fellow, Block was part of a team that was the first to use a heavy liquid chamber to measure neutrino interactions. His experimental team was the first to measure the relative parity of two strange particles, demonstrating that the - parity is odd. In 1972–1973 he was a NATO Fellow in Giuseppe Cocconi's lab at CERN.

After 1964, during summers and winters, Martin and Beate Block were in Aspen, in Geneva, Switzerland where Martin worked at the CERN particle accelerator, or in Evanston, Illinois where he taught and did research. In 1985, Martin Block started the first Aspen Winter Physics Conference with Beate Block in charge of logistical planning, lodging, events and entertainment. As the conferences grew larger, she left all of the planning to professional staff.

After moving to Aspen with his wife, Block did research in theoretical and computational physics.

Block died on July 22, 2016, in Los Angeles, California. Upon his death he was survived by his widow, a son Steven Block, a daughter, and two grandchildren.
