George Caleb Bingham (1811-18790) was born and spent his early childhood in Virginina, His family moved to Missouri. Trained as a cabinet maker, Bingham found early success as a self taught portrait painting. On the frontier and in most of colonial America portraits were the most common sort of painting.
In 1856 Bingham traveled to Dusseldorf and became part of an expatriate artists community there. He became a friend and was influenced by Leutze. Bingham is another example of an American painter whose work was heavily influenced by the German rather than the French school.
Bingham painted many political scenes and was part of that world himself. He was elected treasurer of the state of Missouri.
