Final answer:
Louis Ganne was a French composer and conductor, not to be confused with Louis Leborgne, also known as Patient Tan. Ganne's notable works include 'Marche Lorraine' and the operetta 'Les Saltimbanques'. He was an influential figure in French music during the late 19th and early 20th centuries.
Step-by-step explanation:
The details provided seem to be about Louis Leborgne, often referred to as "Patient Tan" because that was the only syllable he could speak. He is well-known in history due to his association with Paul Broca, a French physician who studied his case. However, the question asked about Louis Ganne, who is a different historical figure. Louis Ganne was a French composer and conductor, best known for his operettas and ballets. Born on April 5, 1862, in Buxières-les-Mines, Allier, he was a leading composer in the French music scene at the turn of the 20th century. Ganne's compositions include the famous 'Marche Lorraine' and the operetta 'Les Saltimbanques'. Despite sharing the same first name and nationality, Louis Leborgne and Louis Ganne are not related in terms of professional achievement or contribution to history.
