1691, spent most of year in Geneva teaching differential calculus to J. Christoph. Fatio-de- Duillier.

1692, taught infinitesimal calculus to Marquis de L'Hospital, for which L'Hospital "generously compensated" him; L'H. gave Bernoulli a "considerable fee" to continue the lessons by correspondence after Bernoulli returned to Basel.

Around 1692, also taught Varignon.

1694, with Leibnitz's help, Bernoulli was to receive a call as Mathematician to the Academy at Wolfenbüttel but his impending marriage prevented it.

1695, was offered professorship at Halle -- declined.

1695-1705, through the intervention of Huygens, got the chair of math and physics at Groningen.

Date? repeatedly was offered positions at Utrecht and Leiden (through his father in law?).

Oct. 1703, his father-in-law got him the Basel Chair in Greek (a sinecure used to get hold of him until he could get an appropriate chair).

1705 got (recently deceased brother Jakob's) chair of math at Basel; the University Senate visited Johann in corpore to ask him to take up Jakob's vacant chair; the government granted him an extraordinary pay raise (ausserordentliche Zulage); held the position until he died.

All during his time at Basel he refused calls to Leiden, Padua, Gröningen, and Berlin.
