From: J.J. O'Connor and E.F. Robertson, "Johann Bernoulli" article on website of the School of Mathematics and Statistics, University of St Andrews, Scotland (http://www-history.mcs.st-andrews.ac.uk/history/Mathematicians/Bernoulli_Johann.html; viewed 26 September 2005):
Johann Bernoulli [the father of Daniel Bernoulli] was the tenth child of Nicolaus and Margaretha Bernoulli... As to his education as a child, Johann wrote in his autobiography that his parents:
"...spared no trouble or expense to give me a proper education in both morals and religion."
This religion was the Calvinist faith which had forced his grandparents to flee from Antwerp to avoid religious persecution.
...Johann Bernoulli had married Drothea Falkner and their first child was seven months old when the family departed for Holland on 1 September 1695. This first child was Nicolaus Bernoulli who also went on to become a mathematician... two other of Johann's children went on to become mathematicians, Daniel Bernoulli, who was born while the family was in Groningen, and Johann Bernoulli.
