Johann Georg Leopold Mozart (November 14, 1719 – May 28, 1787) was a German composer, violinist, and music theorist. He is best known today as the father and teacher of Wolfgang Amadeus Mozart, and for his violin textbook Versuch einer gründlichen Violinschule (1756).
In 1740, Mozart began his career as a professional musician, becoming violinist and valet to one of the university's canons, Johann Baptist, Count of Thurn-Valsassina and Taxis. This was also the year of his first musical publication, the six Trio Sonatas, Opus 1.These were titled Sonate sei da chiesa e da camera; Leopold did the work of copper engraving himself. He continued to compose, producing a series of German Passion cantatas.
In 1747, he married Anna Maria Pertl, who bore him seven children, although only two of them survived past infancy:
Johann Leopold Joachim (August 18, 1748 – February 2, 1749)
Maria Anna Cordula (June 18, 1749 – June 24, 1749)
