Sylvius Leopold Weiss (12 October 1687 – 16 October 1750) was a German composer and lutenist.Born in Grottkau near Breslau, the son of Johann Jacob Weiss, also a lutenist, he served at courts in Breslau, Rome, and Dresden, where he died. Until recently, he was thought to have been born in 1686, but recent evidence suggests that he was in fact born the following year.[1Weiss was one of the most important and most prolific composers of lute music in history and one of the best-known and most technically accomplished lutenists of his day. He was a teacher to Philip Hyacinth, 4th Prince Lobkowicz, and the prince's second wife Anna Wilhelmina Althan.
