Who is J. Robert Oppenheimer?

J. Robert Oppenheimer is an American theoretical physicist who has had a major influence on Physics research. J. Robert Oppenheimer was born on April 22nd, 1904 in New York City to J. Oppenheimer, a wealthy Jewish textile importer who came from Germany, and Ella Friedman, whose parents were immigrants from Hungary. J. Robert Oppenheimer grew up in an upper-middle-class neighborhood on the west side of Manhattan and attended school at the Ethical Culture School where there was no division between academic subjects and religious studies.

J. Robert Oppenheimer had a difficult childhood because he was shy and socially awkward which made him feel more of an outcast at school. J. Robert Oppenheimer's parents opposed him becoming a physicist, but he found his passion for physics when he attended Harvard University in 1922 where he studied under the supervision of J. J. Thomson. J. J Thomson's research on the electron and J. Robert Oppenheimer's own research on X-Ray diffraction drew him to study physics instead of pursuing chemistry. J. Robert Oppenheimer graduated from Harvard University in 1925 with a bachelor's degree and went into a Ph.D program at the University of Gottingen in Germany where J. Robert Oppenheimer learned Quantum mechanics under J. Franck and J. were Born for two years between 1926-1928 before he received his Ph.D. in physics at the University of Gottingen.

J. Robert Oppenheimer had a major role in forming The Manhattan Project, which lead to the Atomic Bomb. J. Robert Oppenheimer was later involved in politics after WWII by trying to stop nuclear proliferation.
