The main characters
We know very little on his childhood
and adolescence. A peasant by birth, he soon left his family, journeying
through various parts of France and making his living as a tutor.
He arrived in Paris in 1628 and put himself in touch with the Mersenne
circle, who immediately held him in great esteem. Launching himself
into the Parisian world, Roberval obtained the chair of philosophy
at the Collège Royal in 1634, then switched to teaching mathematics
in 1655. In 1666, he was one of the founder members of the Académie
des Sciences in Paris.
