Pierre Monichon
Pierre Monichon (24 October 1925 – 1 September 2006) was a French accordionist, musicologist and inventor of the harmoneon (also concert accordion). He published several books on the history of the Accordion, and was a professor at both the CRR93, where he taught a course on the concert accordion and the Conservatoire National de la Région Aubervillers, where he was a professor of the history of music. Monichon was a member of the Ordre des Arts et des Lettres for his contributions to music, achieving the rank of "Chevallier" in 1982. Biography 

Pierre Monichon was born in Lyon, France on 24 October 1925. He trained at the École César-Franck under Yves Margat, studying the piano, counterpoint and the history of music. From 1945, Monichon tried to promote the accordion among classical musicians, inventing the harmoneon in 1948 to solve some of the problems he saw in traditional accordions - namely the stradella bass system, fixing this by creating his own keyboard layout. He then formed several societies for its promotion, as well as teaching it with his student, Charles Taupin at the Paris Conservatory, in a course that exists to this day. Research 
Monichon was a pioneering researcher on the history of free reed instruments - his thesis at École César-Franck was the first in France on the subject of the accordion. Pierre wrote several books on the history of accordions:
