LeCoultre Music Box Instruments
Credit for inventing the cylinder music box, circa 1790, is usually given to David LeCoultre, of Brassus, Switzerland. His descendent Francois Charles LeCoultre (1801 to 1850), also a maternal nephew of Isaac Daniel Piquet, founded his company in 1828. He was succeeded by his son, Charles Francois LeCoultre in 1865, who ran it until circa 1871, when it became Perrelet & Co.
