I am convinced that the patronage from the city fathers of Utrecht had to be connected with medical practice, but so far we find no mention of it. He did practice on campaign with Morosini.
Before 1693, worked with pharmacists while studying with them. He was sort of an itinerant physician/pharmacist.
1693, physician to Francesco Morosini during his military campaign.
1694, became Privatdozent in chemistry at Utrecht.
April 1695, City Fathers of Utrecht provided him with a laboratory.
1698, became Lector in Chemistry at Utrecht, starting salary of 250 guilders, various raises later brought it to 600 guilders.
1703, promoted to extraordinary professor of chemistry.
Also received various lump sums for the dedication of some of his published works.
