Pierre Lacotte was a French ballet dancer, choreographer, teacher, and company director. He specialised in the reconstruction of lost choreographies of romantic ballets.

Ondine, ou La naïade is a ballet in three acts and six scenes with choreography by Jules Perrot, music by Cesare Pugni, and a libretto inspired by the novel Undine by Friedrich de la Motte Fouqué. Pugni dedicated his score to Augusta, Duchess of Cambridge, a long-time balletomane and patron of the arts in London. Whilst the original London production used the title Ondine, ou La naïade, Perrot staged a revival of the ballet under the title, La naïade et le pêcheur, a title which was used for all subsequent productions of the ballet.
