His parents were Julius Oppenheimer and Ella Friedman. His father was a German textile importer. His mom painted. He had one brother, Frank, who likewise became a physicist. His family was very rich and even had several Van Gogh paintings in their house. As a young child, he loved math and science, and was also very shy. He picked up languages quickly and studied Greek, Latin, Dutch, German, and French. His early schooling was at the Ethical Culture School of New York. He studied chemistry, math, physics, languages, and mineralogy. He graduated in 1921 at the top of his class. He married Katherine Harrison in November of 1940. He died in 1967 from throat cancer.
He contracted colitis in 1921, which delayed his entry into Harvard after graduating. He began college at Harvard in 1922, majoring in chemistry, however, further studied a broad range of topics, from mathematics to philosophy. Percy Bridgman, one of his physics professors, caused his interest to shift from chemistry to physics. He continued his study in chemistry and graduated from Harvard in 1925 with a chemistry degree summa cum laude. His education helped him reach his momentous achievement by interesting him in physics and giving him the background information to create the …show more content…
At the University of Gottingen he worked with Max Born to create a paper called the Born-Oppenheimer Approximation, which discussed electronic motion as negligible in mathematical calculations. He worked on theoretical astronomy, including cosmic rays, the stability of neutron stars, and quantum tunneling, which expanded his thinking to new topics and gave him more understanding of nuclear physics. He developed a theory with Melba Phillips which is still used today, called the Oppenheimer-Phillips process, that explains artificial radioactivity in heavy nucleuses. He got most of his experience with radioactive materials and their characteristics by writing many of these
