Bruce Lee Rothschild (born August 26, 1941)[1] is an American mathematician and educator, specializing in combinatorial mathematics.
He is a professor emeritus of mathematics at the University of California, Los Angeles.
He earned a Ph.D. from Yale University in 1967 under the supervision of Øystein Ore.[2] Rothschild, together with Ronald Graham, formulated one of the most monumental results in Ramsey theory, the Graham–Rothschild theorem.
[3] He has collaborated with American mathematicians Joel Spencer and Ronald Graham on key texts related to Ramsey theory.
[4] In 1971, Rothschild shared the Pólya Prize (SIAM) with four other mathematicians for his work on Ramsey theory.
