Augustus Koopman is known for painting scenes of France and the American West. As part of a large community of American expatriate artists in turn-of-the century Paris, Koopman spent a great deal of time at the coast in Etaples near Belgium, where the great Eugene Boudin frequented. It is along this coast that Koopman painted many scenes of the marine activities and people at their roles.
The first steps of his art education took him through the Pennsylvania Academy of Fine Arts, and then on to several Parisian groups. While in France, he did travel widely to other countries, but he recorded his belief that the Boulogne coast of Northern France was the most picturesque in the world. He would rather late in his cut-short life and career, visit the Grand Canyon, and his painting of it is in the Santa Fe Railroad Collection, while several of his images are in the collections of the Congressional Library and New York Public libraries.
