American physicist. He studied
mechanical engineering as an
undergraduate and then carried out his
graduate studies in theoretical physics
at the University of Rochester,
completing his Ph.D. in 1960. Schnitzer
began work as a postdoc instructor at
Brandeis in 1961. He analyzed hadron
physics from a phenomenological
perspective. He tried to organize data
gathered from experiments, especially
on decay patterns in weak interactions,
in order to ascertain symmetries.
At first, Schnitzer worked
mainly on current algebra, and then on
field
theory, under the influence of Steven
Weinberg. Schnitzer collaborated with
Ira Gerstein and Gerald Guralnik,
calculating to 4th order the magnetic
mass difference of pions. Looking for
scale anomalies, Schnitzer carried out
important early calculations on
renormalization processes. And, with
his postdoc Bert Ovrut, he did
influential work in formulating
"effective field theories." Since the
mid1980s Schnitzer has worked
primarily on string theory.
Howard Schnitzer
is the Edward and Gertrude Swartz
Professor of Theoretical Physics at
Brandeis University.
