arl Ditters von Dittersdorf (2 November 1739 – 24 October 1799) was an Austrian composer, violinist and silvologist. He was a friend of both Haydn and Mozart.Dittersdorf was born in the Laimgrube (now Mariahilf) district of Vienna, Austria, as August Carl Ditters. His father was a military tailor in the Austrian Imperial Army of Charles VI, for a number of German-speaking regiments. After retiring honorably from his military obligation, he was provided with royal letters of reference and a sinecure with the Imperial Theatre. In 1745, the six-year-old August Carl was introduced to the violin and his father's moderate financial position allowed him not only a good general education at a Jesuit school, but private tutelage in music, violin, French and religion. After leaving his first teacher, Carl studied violin with J. Ziegler, who by 1750, through his influence, secured his pupil's appointment as a violinist in the orchestra of the Benedictine church on the Freyung.
