Joseph Leopold Eybler

Joseph Leopold Eybler (February 8, 1765 – July 24, 1846) was an Austrian composer and contemporary of Mozart.

Eybler was born into a musical family in Schwechat near Vienna. His father was a teacher, choir director and friend of the Haydn family. Joseph Eybler studied music with his father before attending Stephansdom (the cathedral school of St. Stephen's Boys College) in Vienna. He studied composition under Johann Georg Albrechtsberger, who declared him to be the greatest musical genius in Vienna apart from Mozart. He also received praise from Haydn who was his friend, distant cousin and patron.

In 1792 he became choir director at the Karmeliterkirche (Carmelite Church) in Vienna. Two years later he moved to the Schottenkloster, where he remained for the next thirty years (1794-1824). Eybler also held court posts, including that of court Kapellmeister (chapel master) (1824–33). The Empress Marie Therese commissioned many works from him, including the Requiem in C minor (1803).

Through Joseph Haydn, Eybler met Mozart, who gave him some lessons and entrusted him with the rehearsal of his opera Così fan tutte. Eybler also conducted some performances of Così fan tutte.

On May 30, 1790 Mozart wrote a testimonial for the young Eybler: "I, the undersigned, attest herewith that I have found the bearer of this, Herr Joseph Eybler, to be a worthy pupil of his famous master Albrechtsberger, a well-grounded composer, equally skilled at chamber music and the church style, fully experienced in the art of the song, also an accomplished organ and clavier player; in short a young musician such, one can only regret, as so seldom has his equal."

Mozart and Eybler remained friends to the end. As Eybler wrote: "I had the good fortune to keep his friendship without reservation until he died, and carried him, put him to bed and helped to nurse him during his last painful illness."
