Léon Charles François Kreutzer

In 1840 he began writing for the French publication L’union on the history of opera, and other topics related to that art form.

In 1849 he began working as a music critic for François-Joseph Fétis's Revue et gazette musicale de Paris; publishing a series of articles in that magazine from February 4 and September 23, 1849.

After this he worked as a music critic for a number of 19th century French magazines, including L’opinion publique, Le théâtre, and Revue contemporaine (from 1854).

He contributed several articles to the French language encyclopedia Encyclopédie du XIXe siècle (later published as Essai sur l’art lyrique au théâtre in Paris, 1849).
