Leopold Mozart, a native of Augsburg, then an Imperial Free City in the Holy Roman Empire, was a minor composer and an experienced teacher. In 1743, he was appointed as fourth violinist in the musical establishment of Count Leopold Anton von Firmian, the ruling Prince-Archbishop of Salzburg. Four years later, he married Anna Maria in Salzburg. Leopold became the orchestra's deputy Kapellmeister in 1763. During the year of his son's birth, Leopold published a violin textbook, "Versuch einer gründlichen Violinschule", which achieved success.
