Étienne Pascal (Clermont, May 2 1588 - Paris, September 24 1651) was the
father of Blaise Pascal. He
also had three daughters, two of whom survived past childhood:
Gilberte (°1620) and
Jacqueline
(°1625). His wife Antoinette Begon died in 1626.
He was a local judge and member of the
petite noblesse,
who also had an interest in science and mathematics. He taught his
son himself.
Étienne Pascal served on a scientific committee (whose members
included
Pierre Hérigone and
Claude Mydorge) set up to determine
whether
Jean-Baptiste Morin's
scheme for determining
longitude from the
Moon's motion was practical.
The
Limaçon was first studied and named
by Étienne Pascal and so this mathematical curve is often called
Pascal's Limaçon.
