Benjamin Muckenhoupt (December 22, 1933, Boston – April 13, 2020, Whippany, New Jersey) was an American mathematician, specializing in analysis. He is known for the introduction of Muckenhoupt weights.^[1]

After graduating in 1950 from Newton High School (renamed in 1974 Newton North High School),^[2] Benjamin Muckenhoupt matriculated at Harvard University. where he graduated in 1954 with an A.B.^[3] At Harvard, by his outstanding score on the 1954 William Lowell Putnam Competition, he became a Putnam Fellow.^[4] At the University of Chicago, he graduated in 1955 with an M.Sc. and in 1958 with a Ph.D.^[3] His Ph.D. thesis On certain singular integrals^[5] was supervised by Antoni Zygmund.^[6] In the department of the mathematics of Rutgers University, he was an associate professor from 1963 to 1970 and a full professor from 1970 to 1991, when he retired as professor emeritus.^[3] For many years, he suffered from progressive supranuclear palsy.^[7]

The main focus of Muckenhoupt's mathematical research was harmonic analysis and weighted norm inequalities.^[8] At the Institute for Advanced Study, he held visiting positions for the academic years 1968–1970 and 1975–1976. At the State University of New York at Albany he was a visiting professor for the academic year 1970–1971.^[3]

His doctoral students include Eileen Poiani.^[6]

Upon his death he was survived by his widow, a daughter, a son, and three grandchildren.^[4]
