Franz Ignaz Danzi was a German cellist, composer and conductor, the son of the noted Italian cellist Innocenz Danzi. Born in Schwetzingen and raised in Mannheim, Danzi studied with his father and with Georg Joseph Vogler before he joined the superlative orchestra of the Elector Karl Theodor in 1778 as a teenager. In 1780 the first of his woodwind compositions was published at Mannheim. His father, principal cellist of the orchestra, was praised by Mozart for his playing at the premiere of Idomeneo. Danzi remained behind in a Mannheim that was rendered more provincial when Karl Theodor moved his court to Munich in 1778. After an apprenticeship with the small theater orchestra left in Mannheim, he rejoined the main court in Munich as principal cellist—taking his father's position—in 1784. Danzi's career coincided with the original of much of the current concert hall music: he knew and admired Mozart, was a contemporary of Beethoven, and tutored Carl Maria von Weber, whose music he respected and promoted.
