(Born: Stein, near Krems, Austria, 14 January 1800; Died: Vienna, Austria, 3 June 1877) Austrian botanist, mineralogist & music bibliographer.

Köchel worked as tutor while attending law school at Vienna University, from which he graduated in 1827. Afterward he became tutor to the four sons of Archduke Carl. On completion of this duty his services were recognized by the award of the Knight's Cross of the Order of Leopold in 1842. Köchel travelled much in pursuit of botany and mineralogy and become a recognized authority in both fields. He wrote, Chronologisch-thematisches Verzeichnis sämtlicher Tonwerke Wolfgang Amade Mozarts (Leipzig, 1862), the first comprehensive bibliography of Mozart's compositions-to this day still known by their Köchel number.
