Anton Weidinger

Anton Weidinger (June 9, 1766, Vienna - September 20, 1852, Vienna) was an Austrian trumpet virtuoso in the classical era.

Basing his ideas on earlier designs, in 1792, Weidinger experimented with a 5-keyed trumpet, a version of the instrument on which a full chromatic scale became possible, albeit with some loss of the instrument's usual power. It remained fashionable well into the 19th century when it was superseded by the valve trumpet.

In 1799 Weidinger became a member of the Imperial and Royal Court Trumpeter Corps.

In 1796 Joseph Haydn composed his Concerto in E-Flat Major for Trumpet and Orchestra for Weidinger, the first piece by Haydn developed for a trumpet solo. The first performance took place in Vienna at the Old Burgtheater (now demolished) on 22 March 1800. Johann Nepomuk Hummel who was Haydn's successor as Kapellmeister to the Esterházy family also composed a Concerto for Trumpet and Orchestra for Weidinger; this was originally written in the key of E Major, but is much more commonly played in the key of E-Flat Major. Hummel also wrote a Trio for trumpet, piano and violin for Weidinger. Unfortunately this is now lost. Other composers known to have written for Weidinger include Leopold Kozeluch and Joseph Weigl (1766-1846).
