Norman Levinson

Norman Levinson, born in Lynn, Massachusetts on August 11, 1912 and died in Boston on October 10, 1975, was an American mathematician whose work covered Fourier transforms, complex analysis, non-linear differential equations, number theory and signal processing. He took bachelor's and master's degrees in electrical engineering at the Massachusetts Institute of Technology in 1934, studied under Norbert Wiener, and received his PhD in mathematics from MIT in 1935 after a fellowship year at the University of Cambridge. He joined the MIT faculty in 1937, won the Bocher Memorial Prize in 1954 and the Chauvenet Prize in 1971, and in 1974 proved that more than a third of the zeros of the Riemann zeta function lie on the critical line. The Levinson recursion, held in this atlas as an algorithm, carries his name.
