Arthur Quentin de Gromard

Gromard lived in Eu, Seine-Maritime, founded a philharmonic society (the Cécilienne) in 1857, and he was the inventor of a musical instrument, called the cecilium (1861).

"[2] A peculiar free reed and keyboard instrument invented by Quantin de Crousard and exhibited in Paris in 1867.

[3]It was described in the Crosby Brown Collection: A pear-shaped case of red wood with flat back and short neck, in which are 78 ivory touches arranged in 6 rows of 13 each.

These touches operate a series of free reeds, which, with the bellows, are concealed within the case.

Wind is supplied to the bellows by a handle working through an opening in the lower part of the front of the case.
