Oscar Sala


Oscar Sala, Italian-Brazilian nuclear physicist and important scientific leader, Emeritus Professor of the Institute of Physics, University of São Paulo.

Early life and education

Sala graduated in physics in 1943, at the then recently created University of São Paulo, in São Paulo, Brazil. The Department of Physics of the Faculty of Philosophy, Sciences and Letters was started with two imminent Italian physicists, Gleb Wataghin and Giuseppe Occhialini, who specialized in researching cosmic radiation. He was contemporary with a brilliant generation of young Brazilian physicians, such as César Lattes, José Leite Lopes, Mário Schenberg, Roberto Salmeron, Marcelo Damy de Souza Santos and Jayme Tiomno. While still a student, Oscar Sala started research work with the group. In 1945, Sala published with Wataghin an important paper on showers of penetrating nuclear particles.

Career in academia

Soon after graduation, he was hired as a teaching assistant by the Chair of General and Experimental Physics, led by Prof. Marcelo Damy de Souza Santos. His entire scientific and teaching career was spent at the same institution, which later became the Institute of Physics. In this new capacity, Sala became head of the Department of Nuclear Physics.
In 1946 Oscar Sala received a scholarship from the Rockefeller Foundation and went to study in the U.S., first at the University of Illinois, and subsequently, in 1948, at the University of Wisconsin–Madison. There, he participated in the development of electrostatic particle accelerators for use in nuclear physics research, the first devices to use pulsed beams for the study of nuclear reactions with rapid neutrons. Upon his return to Brazil, Sala was responsible for installing and coordinating research efforts based on a large electrostatic Van de Graaff generator. Later, he helped to build a pelletron at the University of São Paulo.
As a scientific leader, Dr. Oscar Sala was one of the founders and a scientific director with the Foundation for Support of Research of the State of São Paulo and president of the Brazilian Society for the Advancement of Science. He was a member of the Brazilian Academy of Sciences, the Third World Academy of Sciences and the American Academy of Arts and Sciences. Prof. Sala was a member of the Board of Sponsors of The Bulletin of the Atomic Scientists.
