The Trials of J. Robert Oppenheimer

 J. Robert Oppenheimer
(April 22, 1904 – February 18, 1967)
 was an American theoretical physicist and professor of physics at the University of California, Berkeley. He is best known for his role as the scientific director of the Manhattan Project, the World War II project that developed the first nuclear weapons, for which he is often referred to as the "father of the atomic bomb".

As a teacher and promoter of science, Oppenheimer is remembered most for being the chief founder of the American school of theoretical physics while at the University of California, Berkeley, contributing significantly to the rise of American physics to its first era of world prominence in the 1930s. After the second World War, he contributed to American scientific organizations again, as director of the Institute for Advanced Study in Princeton, where he held Einstein's old position of Senior Professor of Theoretical Physics.
