Édouard(-Marie-Ernest) Deldevez (May 31, 1817 – November 6, 1897) was a French violinist, conductor, composer, and music teacher. He is also known as Ernest or Ernst Deldevez. The names Edmé or Émile are occasionally substituted for Edouard.
Édouard Deldevez was born and died in Paris, France. He won many prizes as a violinist. He became part of a group of musicians centred on François Sudre (1787 - 1864) who were attempting to develop a way of transmitting language through music. Sudre trained Deldevez and Charles Lasonneur to play and interpret his alphabet. A given note would represent a word or a letter of the alphabet. The trio troured France, answering questions from the audience using Sudre's violin. A military application quickly presented itself. A bugler on a battlefield could transmit orders to a regiment by playing an appropriate tune. This promising hypothesis came to nothing because the system was too vulnerable to wind and weather.
Clearly grasping at straws, Sudre then offered the military a set of musical cannons, but they declined the suggestion. In 1829 Sudre began to develop the system that is now known as the Do Re Mi method of notating music. In 1867 Deldevez published "Notation de la musique classique." He wrote many other books and was awarded the Legion d'Honneur in 1874.
Today, Deldevez is best known for writing the ballet Paquita (1846). In 1881, Marius Petipa included additional numbers in his revival of the ballet, this time written by Ludwig Minkus (1826-1917).
