Baldung was from a family of lawyers, doctors, professors and was the only male member of his family not to receive a university education. From 1503 to about 1507 he worked as a journeyman with Dürer, and it was probably from Dürer that Baldung acquired his nickname Grien, perhaps to distinguish him from the other 'Hans' in Dürer’s workshop at the time - Hans Shäufelein, Hans von Kulmbach, and Dürer’s younger brother, Hans. It has been postulated that the name came from Baldung’s preference for wearing green, and Baldung subsequently incorporated a G into his monogram. In 1509 he moved to Strasbourg, but remained lifelong friends with Dürer. Though influenced by Dürer, Baldung was a highly original artist and quickly established his own style and subject matter. He was also one of the first artists to make chiaroscuro colour-printed woodcuts.
