- He worked initially for 16 years in his native region as an apothecary.
- After receiving his M.D., he moved to Vienna, where he apparently stayed for the rest of his life. He reportedly taught chemistry and was physician to the court, but these reports are undocumented. Nevertheless, in the silence I assume, especially in light of his background as apothecary, that he put the medical degree to use.
