DETAIL
He was mostly self-taught, which helps to explain his unique manner of painting. Here we have a direct link to the Chromatic Chiaroscuro Coloristic Painting in the manner of Velasques.

Later he would become a Full Professor at the Munich Academy, leading the Munich School Painters to a more coloristic approach.
Wilhelm was also the teacher of Frank Duveneck and his circle, leading the movement that would dislodge the Hudson River School with its freedom of paint application. Wilhelm was most definitely one of the lead actors in the development of American Impressionism.

It is no real coincidence that William Turner Dannat studied at the Munich Academy and was a major influence on the Boston School Painters Edmund Tarbell, and Frank Weston Benson. Of course Decamp the other founding father of the Boston School was also a student of von Diez which completes the circle.
