Name:
Named in 1969 by Theodore E. Bunch and Louis H. Fuchs in honor of Maria Aristides Brezina [May 4, 1848 Wien (Vienna), Austria – May 25, 1909 Wien (Vienna), Austria], past Director of the Mineralogy-Petrology Section of the Natural History Museum, Vienna, Austria. Brezina was one of the most important researchers of meteoritics and helped develop an important early classification of meteorites.
