Hans Sitt (born Jan Hanuš Sitt on 21 September 1850, Prague – 10 March 1922, Leipzig), was a Bohemian violinist, violist, teacher, and composer. During his lifetime, he was regarded as one of the foremost teachers of violin. Most of the orchestras and conservatories of Europe and North America then sported personnel who numbered among his students. Sitt was born in Prague the son of Anton Sitt (originally Szytt) the Elder (1819–1878), a prominent Hungarian-born violin maker. Sitt's musical talent manifested itself early and from all accounts, he could easily have enjoyed the typical career of a “wunderkind” had his parents chosen to exploit him, but they wisely refused this course. Instead, he was allowed to have a normal life and received a regular education at a gymnasium (high school) before being sent to the Prague Conservatory. From 1884 to 1921 Sitt held the august position of Professor of Violin at the Leipzig Conservatory, and authored several important studies for violin and viola, some of which are still used. He was conductor of the Leipzig Bach Society (Bach-Verein Leipzig) from 1885 to 1903. Sitt played the viola in the Brodsky Quartet of Leipzig from 1883 to 1895 along with Hugo Becker, Julius Klengel, and founder Adolph Brodsky.
