Steven Weinberg

Steven Weinberg (/ˈwaɪnbɜːrɡ/; May 3, 1933 – July 23, 2021) was an American theoretical physicist. He shared the 1979 Nobel Prize in Physics with Abdus Salam and Sheldon Glashow "for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current".

He held the Josey Regental Chair in Science at the University of Texas at Austin, where he was a member of the Physics and Astronomy Departments. His research on elementary particles and physical cosmology was honored with numerous prizes and awards, including the 1991 National Medal of Science. In 2004, he received the Benjamin Franklin Medal of the American Philosophical Society, with a citation that said he was "considered by many to be the preeminent theoretical physicist alive in the world today." He was elected to the U.S. National Academy of Sciences, Britain's Royal Society, the American Philosophical Society, and the American Academy of Arts and Sciences. His three-volume textbook The Quantum Theory of Fields is considered a classic. He later became interested in general relativity and wrote Gravitation and Cosmology.
