I recall reading:

E.J. Wegman and I.W. Wright. Splines in Statistics. Journal of the American Statistical Association, vol 78, N382, 1983.

which mentioned `spline' as a tool that draftsmen used to draw curves, but the description does not match the french curve I know, which _is_ a template-like piece of various curvature. (I used one of these in the year I spent in Architechture school right after high school. No, I not _that_ old... I believe they are still in common used today.)
