||40 years ago, I`ve started collecting minerals, fossils and ancient artefacts. Since 1990, I`m engaged in studies concerning the two big,german meteor craters:Nördlinger Ries and Steinheimer Becken. During my hollidays-about three times a year-I`m travelling to this countrysides to do field research. Working in the field of meteorite impacts.collecting meteorites suggests itself. so my meteorite collection grows rapidly over the years,to meanwhile more than 150 falls/founds(including Moon,-Mars and Vesta orgins. I`m also the owner of 5 Main-masses.
