He studied art at the academies of Stuttgart and München, and settled down in München (1908) for most of his life. He was part of the Munich Secession and was a leading figure, in addition to taking part in exhibitions.

After the First World War he found many projects in church restoration, making coloured woodcuts based on Old Testament topics. He was named Professor in 1928 - and a degenerate artist in 1937.

He is perhaps most famous for St. Karl's Church in Nürnberg. There he used a thin paint containing casein to keep the structure of the stone in the walls, at the same time as allowing his figures to be identifiable.
