Eugene (Gene) Jarosewich (1926–2007) was a chemist in the Department of Mineral Sciences at the Smithsonian Institution.[1] Gene was known worldwide for his wet chemical analyses of meteorites.
Working with specimens from the National Mineral Collection, Gene and his co-workers also developed a set of commonly used standards for electron microprobe analyses.
The mineral Jarosewichite and asteroid 4320 Jarosewich are named in his honor.
