Abraham Charnes (September 4, 1917 – December 19, 1992) was an American mathematician who worked in the area of operations research.
Charnes published more than 200 research articles and seven books, including An Introduction to Linear Programming.
In his 1953 article with William W. Cooper he developed the chance constrained programming method for solving optimization problems in the presence of uncertainty.
In 1982 he was awarded (jointly with William W. Cooper and Richard Duffin) the John von Neumann Theory Prize.
Charnes also received the Distinguished Public Service medal from the U.S. Navy for his contributions as a research physicist and operations analyst during World War II.
