Pierre Bézier worked at Renault where he developed CAD software using piecewise polynomial curves in the 1960s. Paul de Casteljau independently (starting in 1959) worked on the same subject at Citroën, but didn’t publish until later. De Casteljau’s control scheme is actually what we use today, not Bézier’s. We should probably call these De Castlejau curves or De Castlejau–Bézier curves if we want to give fair attribution. He does get his name on the De Castlejau algorithm (lerp, lerp, lerp, ...) for evaluating such curves.
