Pierre Bézier (September 1st 1910 with Paris - November 25th 1999) is a Engineer in Mécanique and electricity. It is especially known for its invention of the curved and surfaces of Bézier usually used in Informatique.

Graduate of the 3Ecole Nationale Sup3erieure of arts and trades in 1930 and of the University of electricity (Supélec) in 1931, it receives the title of doctor in mathematics of the Université of Paris in 1977.

Entered at Renault in 1933, it will make there all its career until in 1975 at the position of director of the mechanical methods. It designs there in 1945 transfer machines for the production line of the Renault 4CV and in 1958 one of the first machines to Numerical control of Europe.

Its concern was to create simple means and powerful to model forms and to facilitate the programming of the machines with numerical control. Its research led to a software, Unisurf, which is at the base of all the software created thereafter. The concepts of CAD and CFAO had just taken form.

Following disagreements with its hierarchy, it was put at the variation, which gave him time to be interested in the modeling surfaces.

He taught the Productique with the Conservatoire national of arts and trades of 1968 with 1979.

He conceived the blue Pyrex for Newell.
