Steinberger, Jack, 1921–, American physicist, b. Kissingen,
Germany, Ph.D. Univ. of Chicago, 1948. He was a professor at
Columbia from 1950 until 1971. In the early 1960s, Steinberger
and co-researchers, Leon Lederman and Melvin Schwartz, developed
the neutrino beam method to study weak interactions and then
discovered a previously unknown type of neutrino (a particle
with no detectable electric charge or mass that moves at the
speed of light). This led to the development of a new scheme for
classifying families of subatomic particles. In 1988, the trio
shared the Nobel Prize in Physics for their work. More on Jack
