Steven Weinberg (born May 3, 1933) is an American theoretical physicist and Nobel laureate in Physics for his contributions with Abdus Salam and Sheldon Glashow to the unification of the weak force and electromagnetic interaction between elementary particles.
Steven Weinberg was born in 1933 in New York City to Jewish immigrants Frederick and Eva Weinberg. He graduated from Bronx High School of Science in 1950 in the same graduating class as Sheldon Glashow, whose own research, independent of Weinberg's, would result in them (and Abdus Salam) sharing the same 1979 Nobel in Physics.
Weinberg received his bachelor's degree from Cornell University in 1954, living at the Cornell branch of the Telluride Association. He left Cornell and went to the Niels Bohr Institute in Copenhagen where he started his graduate studies and research. After one year, Weinberg returned to Princeton University where he earned his Ph.D. degree in Physics in 1957, studying under Sam Treiman. Weinberg is an atheist.
