Great Engineers & Scientists

In 1676, Sir Isaac Newton wrote "If I have seen further it is by standing on ye shoulders of Giants." In this blog, we take Newton's words to heart, and recognize the many great engineers and scientists upon whose shoulders we stand.

So who do you think of when you hear "Great Engineer"? Let us know! Submit a few paragraphs about that person and we'll add him or her to the pantheon. Please provide a citation for the material that you submit so that we can verify it. Please note - it has to be original material. We cannot publish copywritten material or bulk text taken from books or other sites (including Wikipedia).

Pierre Bezier and the Bezier Curve

Posted September 27, 2012 12:00 AM by SavvyExacta

Pierre Bezier was best known for popularizing Bezier curves used in CAD and computer graphics systems. These curves are used to design objects like automobile bodies. Fonts like TrueType and PostScript were designed using Bezier curves.

Bezier came from a family of engineers. He followed in their footsteps and earned degrees in mechanical and electrical engineering from French universities. At the age of 67 he earned a doctorate in mathematics.

Work at Renault

For 42 years Bezier worked at Renault as a tool setter, tool designer, head of the tool design office, director of production engineering, and director of the machine tool division. At Renault, Bezier was responsible for most of the mechanical parts for the Renault 4CV.

Even being a prisoner of war in Germany during WWII did not stop Bezier's innovation. During that time he designed transfer machines for engine block machining. These robot precursors were used by Renault and sold to competitors around the world.

CADCAM Research and the Bezier Curve

Bezier began researching CADCAM in 1960 while working on his UNISURF system. He researched drawing machines, computer control, interactive free-form curve and surface design, and 3D milling.

Bezier curves are commonly used in vector graphics for design software. They help model smooth curves that can be scaled indefinitely. Applications include computer graphic design, animation, and fonts. Bezier patented and popularized Bezier curves and Bezier surfaces.

Recognition was awarded to Bezier for his contributions to computer graphics and interactive technologies when he received a Steve. A Coons Award in 1985. Bezier died on November 25, 1999, and The Pierre Bezier Award in his memory recognizes those with outstanding accomplishments in solid, geometric, and physical modeling and applications.

Bezier Curves, It was something I thought about looking into but never followed through.

Thanks.
