Ernst Gerhard is such a minor artist that we know almost nothing about him beyond the fact that he was born in Landau in south-west Germany, worked mostly in Munich, and exhibited in the Great Berlin Art Exhibition of 1909 with a dark painting of a group of armed men.
Apart from a genre painting of five ducks from much the same period which was auctioned in 2005 and bears his signature, that’s all. If you know more we would love to hear from you.
