Louis-Auguste Buffet (b. 1789), also called Buffet jeune, was a significant maker of woodwind instruments in Paris from at least 1816. Buffet was a supplier of instruments to the band of the Garde Royale; built a bass clarinet with Isaac Dacosta in 1832; in 1837, advertised himself as a maker of a variety of woodwinds; collaborated with Hyacinthe Klosé from 1839 to 1844 to invent the Boehm system clarinet; and in 1844 patented the invention (French patent no. 16,036). Buffet’s son Louis Auguste Buffet (1816–1884) was presumably associated with the firm, which closed in 1885).

Auguste Buffet jeune (full name Louis-Auguste Buffet) was born 6 August, 1789 in La Couture, a younger brother of Denis Buffet-Auger. Auguste was making musical instruments in La Couture by 1813, but by 1830 had moved his workshop to Paris. In the 1830s he designed and built two new bass clarinets, developed an improved Boehm system flute (with flutist Victor Coche), and, with H.E. Klosé, invented the so-called Boehm system clarinet, the system still most commonly in use for clarinets. In the early 1840s, with P.J.R. Soler, he developed a Boehm system oboe; this, however, was less successful. Louis-Auguste Buffet was his son. Auguste Buffet jeune died on 30 Sep 1864 in Anet.
