Richard Allen Hunt (16 June 1937 – 22 March 2009) was an American mathematician.
He graduated from Washington University in St. Louis in 1965 with a dissertation entitled Operators acting on Lorentz Spaces.
An important result of Hunt (1968) states that the Fourier expansion of a function in Lp, p > 1, converges almost everywhere.
The case p=2 is due to Lennart Carleson, and for this reason the general result is called the Carleson-Hunt theorem.
He was a faculty member at Purdue University from 1969 to 2000, when he retired as professor emeritus.
