Jerome Friedman is a Jewish American physicist and winner of the 1980 Nobel Prize in Physics.
Friedman (born March 28, 1930) was born in Chicago to Russian immigrant parents. He studied physics at the University of Chicao and in 1960 he joined the physics faculty at MIT. He eventually headed the school's physics department from 1983 to 1988.
While at MIT, Friedman conducted experiments on a linear accelerator and demonstrated that neutrons and protons were formed of quarks, the fundamental energy packets from which all matter is composed. For this work he was awarded the 1990 Nobel Prize in Physics, which he shared with Henry Kendall and Richard Taylor.
In 2008, Friedman received an honorary Ph.D. from the University of Belgrade.
