	<DD>1691, spent most of year in Geneva teaching differential calculus to J. Christoph. Fatio-de- Duillier.
	<DD>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.
	<DD>Around 1692, also taught Varignon.
	<DD>1694, with Leibnitz's help, Bernoulli was to receive a call as Mathematician to the Academy at Wolfenbüttel but his impending marriage prevented it.
	<DD>1695, was offered professorship at Halle -- declined.
	<DD>1695-1705, through the intervention of Huygens, got the chair of math and physics at Groningen.
	<DD>Date? repeatedly was offered positions at Utrecht and Leiden (through his father in law?).
	<DD>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).
	<DD>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.
	<DD>All during his time at Basel he refused calls to Leiden, Padua, Gröningen, and Berlin.
	<DD>1730 (alone) and 1734 (with son Daniel), won Paris Academy prizes.

	<DD>Belonged to famous family of mathematicians -- worked with his brother Jakob only in his early years.
	<DD>By 1710, had won a good place in Malebranche's mathematical circle in Paris (surely this date is wrong--too late).
