Ronald Graham
Ronald Lewis Graham (October 31, 1935 – July 6, 2020) was an American mathematician. He was born in Taft, California.[1] He was known for his important work in scheduling theory, computational geometry, Ramsey theory, and quasi-randomness.[2] He discovered Graham's number.
He was the Chief Scientist at the California Institute for Telecommunications and Information Technology and the Irwin and Joan Jacobs Professor in Computer Science and Engineering at the University of California, San Diego (UCSD).
Graham died on July 6, 2020 in La Jolla, California from a rare form of a chronic pulmonary disease at the age of 84.[3][4]
