Hans Hirtz
Hans Hirtz or Hirtze was a German painter of the late Gothic period, recognized as a major painter by art historians as early as the 16th century. He was active between 1421 and 1463 in Strasbourg and other areas of the Upper Rhine. His years of birth and death are unknown, though a reference to his widow in a document of 1466 shows he died before that date - the document shows that she remarried to the Strasbourg stained-glass artist Peter Hemmel.
