Petrus Wilhelmi de Grudencz

Petrus Wilhelmi de Grudencz or Piotr of Grudziądz (1392 – ca. 1480) was a medieval composer from Graudenz (Grudziądz), the author of songs and motets. His music represents the culture of Central Europe from the Middle Ages. In 1418 he began his studies at the University of Krakow, after which he worked probably in Vienna, then in the vicinity of Basel. In the 1440s he was a chaplain to Frederick III in Vienna, although was not a singer in the chapel but moved principally in various university circles.
