The history of Leblanc dates back to 1750 when Ets. D. Noblet was established in France making instruments for the court of Louis XV. Noblet would help establish France as the center of woodwind manufacturing. In 1904, Noblet found himself with no heir to the family business, and it was sold to Georges Leblanc.

The Leblanc family was known for using scientific acoustic research in the development of clarinets. Georges’ son Leon was an outstanding clarinetist and won the top prize from the Conservatoire de Paris. As an accomplished player, he believed heavily in the scientific principles of manufacturing and brought a high level of consistency and playability to their hand-made instruments.

In 1921, Leblanc began distribution in the US with Gretsch & Brenner in New York. However, the Leblanc family became unhappy with the amount of work involved in making adjustments to the instruments after months of travel at sea from France. In 1946, Vito Pascucci, a repairman for the Glenn Miller band, founded Leblanc USA in Kenosha, Wisconsin and took over the distribution of Leblanc France products in the US. Vito opened a small store front and began building his own student level instrument, leaving Leblanc to focus on the full range of professional instruments.
