Jerzy Franciszek Plebański (7 May 1928, Warsaw – 24 August 2005, Mexico) was a Polish theoretical physicist best known for his extensive research into general relativity and supergravity.
In 1958 Plebański traveled to the United States, and spent two years there, first as an invited professor at the Institute for Advanced Study in Princeton, and then at UCLA in Los Angeles.
In the Cold War years, Mexico was a neutral country, and their visit was approved by the Polish authorities.
Jerzy was invited by Arturo Rosenblueth to join the physics department of the Center for Research and Advanced Studies [Centro de Investigaciones y de Estudios Avanzados] of the National Polytechnic Institute—normally referred to by its initials CINVESTAV—in Mexico City.
During his stay in Mexico he hosted many Polish physicists and maintained close contacts with the University of Warsaw.
