**Dupin** was educated at the École Polytechnique, where he learnt geometry from Monge, he became a naval engineer and was professor at Conservatoire des Arts et Métiers from 1819 until 1864. He made contributions to differential geometry and in particular invented the 'Dupin indicatrix' which gives an indication of the local behaviour of a surface up to the terms of degree two.
