Although Bézier only developed the notation, the algorithm was first developed in 1959 by Paul de Casteljau. Bézier curves consist of nodes with attached control handles, with which the curves are represented in computer software. The control handles define the shape of the curve on either side of the common node, and can be manipulated by the user, via the software.
