Henry Lemoine

Henry Lemoine (21 October 1786 – 18 May 1854) was a French music publisher, composer, and piano teacher.
Life.
Lemoine was born in Paris, where he was a pupil of Anton Reicha, a composer and piano teacher.
In 1816 he took over his father Antoine Marcel Lemoine's music publishing business. His father had founded the company in 1772, and it still exists today under the name of Éditions Henry Lemoine. Lemoine was the publisher for Frédéric Chopin, among many others. In 1844 he also published Hector Berlioz's "Traité d'orchestration". He worked with Ferdinando Carulli to publish a solfège textbook by Adolphe Danhauser called "Solfège des Solfèges," which is still in print. In 1850 Lemoine, then blind, turned over his company to his son Achilles Lemoine.
Lemoine's compositions are today generally regarded as unimportant. His piano method and harmony textbook, however, are still of much interest to students of the instrument. He composed a lot of etudes of all levels. 
Compositions.
Lemoine wrote a number of works of music education (including "Études infantines"), an extensive collection of piano pieces called "Bagatelles" and "Recreations Musicales". His "Méthode et des études de piano" is still in use today.
