George Henry Smillie was an American painter of landscapes. He was the brother of James David Smillie and a student of James McDougal Hart.
Smillie worked in oil paint and water color. His style is often described as Impressionistic. Though he was a skilled draftsman, George Henry Smillie endeavored to communicate feelings and moods through his art more than he did to strive toward perfect and exacting realism. To this end, his composition style often simplifies the elements of the landscapes which he painted and takes more liberty with the use of color and shade, shapes and shadows.
Smillie had an almost spiritual admiration for the simplicity of landscape painting which, reduced to its most fundamental aspects, represents a canvas crossed by a horizontal line. It was in simplicity that Smillie found the inspiration for his most expressive pieces though his use of color and shape betrays a highly developed and sophisticated knowledge of technique.
He painted all over the United States, including the East Coast and the American West. He is associated with the Hudson River School of landscape artists as, even though he wasn't as drawn toward realism as were his peers, his work exhibits the trademark characteristics of that painting school.
