Professional and Biographical Information

Biographical Essay from the 2004 SLAC Employee Service Awards Program, in celebration of Professor Perl's 40th anniversary at SLAC:

Martin's first contact with SLAC was as a participant in the 1962 Summer Study Program while be was on the faculty at the University of Michigan. He joined the faculty here in June, 1963, and later served as faculty Chair. He was the group leader of Group E for many years and more recently he has been Co-Group Leader with Rafe Schindler of Group E. The first experiments carried out by Group E were new-particle searches, including a search for fractionally charged particles. The group then studied Particle production by muon and electron beams. One purpose of the muon experiments was to try to understand the intrinsic difference between the muon and the electron, a difference still unknown. Martin and his group got involved quite early with the prospective physics program at the SPEAR storage ring and, by the turn on of SPEAR in 1972, were collaborating with Group C: and with groups from LBL in the initial use of the SLAC-LBL detector. Martin's main interest was to search for heavy, charged leptons, that is, leptons heavier than the muon and the electron. This led to the discovery by Martin and the SPEAR physicists of the tau lepton in the period 1974-1980. Martin and Group E were also involved in discoveries of the psi particles in 1974 and of charmed particles in 1976. For his discovery of the tau lepton, Martin was awarded the Wolf Prize in Physics in 1982 and the Nobel Prize in Physics in 1995. Since 1980, Martin has been involved in many areas of physics research including studies of the properties of the tau lepton. He is also a member of the BaBar collaboration. Within the last 10 years, he has led unique searches in bulk matter for elementary particles with fractional electric charge using a high technology version of the Millikan Oil Drop Experiment.
