Florian Cajori,
A History of Mathematics
(1893)
“ A contemporary mathematician, whose genius excelled even that of the great Fermat, was Blaise Pascal (1623–1662) . He was born at Clermont in Auvergne. In 1626 his father retired to Paris, where he devoted himself to teaching his son, for he would not trust his education to others. Blaise Pascal's genius for geometry showed itself when he was but twelve years old. His father was well skilled in mathematics, but did not wish his son to study it until he was perfectly acquainted with Latin and Greek. All mathematical books were hidden out of his sight. ”
