Oppenheimer was born in 1904 in New York to a rich German-Jewish family who belonged to the high-minded “Ethical Culture Society”. At school, superior and gauche, he was bullied by the other boys but inspired by a chemistry teacher. At Harvard, after abandoning his literary ambitions, Oppenheimer began taking courses in theoretical physics, winning a Rhodes scholarship to study in Europe, before returning to America to found the school of theoretical physics at Berkeley. There, in 1939, he was writing original papers on neutron stars, predicting the existence of black holes — when in Germany nuclear fission was discovered. Oppenheimer seems to have appreciated the explosive possibilities immediately.
