(4394) Fritzheide Main-belt Asteroid

Discovered on 2 March 1981 by S. J. Bus at Siding Spring.

German mineralogist Fritz von der Heide (1891-1973) studied meteorites at a time when little work was being done on these interesting extraterrestrial samples. His 1934 book Kleine Meteoritenkunde influenced a generation of meteorite researchers and has been reprinted several times and translated into English.Naming citation (20001013/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
