Samios 70th
Nicholas Samios, former Brookhaven director, celebrated his 70th birthday at the laboratory on 16 May. Samios joined Brookhaven in 1959. He became chairman of the laboratory's physics department in 1975, and was named deputy director for high-energy and nuclear physics in 1981. The following year he was appointed director, a position he held for 15 years. Samios is currently deputy director of the RIKEN-Brookhaven research centre. His career in high-energy physics has seen many important contributions to the field. Early on, he was involved in experiments that demonstrated parity violation in hyperon decays. He went on to become a leading player in many particle discoveries, notably those of the Omega minus and the first charmed baryons. These discoveries provided important input to the formulation of Quantum Chromodynamics and the Standard Model.
