Jerome Isaac Friedman (born March 28, 1930) is an American physicist.

He won the 1990 Nobel Prize in Physics along with Henry Kendall and Richard Taylor, "for their pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics.

Jerome Friedman excelled in art but became interested in physics after reading a book on relativity written by Albert Einstein.

In 1968–69, commuting between MIT and California, he conducted experiments with Henry W. Kendall and Richard E. Taylor at the Stanford Linear Accelerator Center which gave the first experimental evidence that protons had an internal structure, later known to be quarks.

[6] Friedman is one of the 20 American recipients of the Nobel Prize in Physics to sign a letter addressed to President George W. Bush in May 2008, urging him to "reverse the damage done to basic science research in the Fiscal Year 2008 Omnibus Appropriations Bill" by requesting additional emergency funding for the Department of Energy’s Office of Science, the National Science Foundation, and the National Institute of Standards and Technology.
