4395 Danbritt           Discovered 1981 Mar. 2 by S. J. Bus at Siding Spring in the course of the U.K. Schmidt-Caltech Asteroid Survey.
As a research professor at the University of Tennessee, Daniel Britt (b. 1950) studies the relationships between minor planets and meteorites using reflectance spectroscopy. He has been instrumental in unraveling the role of shock processes in modifying the reflectance properties of asteroidal surfaces.
