Well, to make a long story short, J. Robert Oppenheimer was Jewish!
Since J. Robert Oppenheimer's mother was Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish. His father was Jewish too.
J. Robert Oppenheimer (whose full birth name was Julius Robert Oppenheimer) was born on April 22, 1904 in New York City, United States. J. Robert Oppenheimer passed away on February 18, 1967 (aged 62).
J. Robert Oppenheimer is often called the ''father of the atomic bomb'' for leading the Manhattan Project, the program that developed the first nuclear weapon during World War II.
