5760 Mittlefehldt           Discovered 1981 Mar. 1 by S. J. Bus at Siding Spring in the course of the U.K. Schmidt-Caltech Asteroid Survey.
David (Duck) Mittlefehldt (b. 1951) of NASA's Johnson Space Center has applied petrologic and geochemical techniques to understanding the origin and evolution of differentiated planets, major and minor. He is a leading expert on both asteroidal basalts and martian meteorites.
