Regarding his training and practice, this link states: "Born in Philadelphia, Schofield attended the Pennsylvania Academy of the Fine Arts, where he studied with Thomas Anshutz, and the Académie Julian in Paris, where his teachers included William-Adolphe Bouguereau. He built lasting friendships with Ashcan School painters Robert Henri, William Glackens, and John Sloan. In 1901 he and his young family moved to England; thereafter, he spent summers in Cornwall and fall through spring in the United States." The last years of his life were spent in England, probably due to the war.
Images of Schofield paintings I found on the Internet dating from his early 40s onward strike me as being impressionistic with regard to use of color, and somewhat inconsistently at that. One image below of a painting done in his late 30s is more purely Impressionist in its colors and brushwork. From around 1910 onwards, Schofield retained a rough brushing style, but made his images more structural by adding outlining and more clearly defined color areas. The result was a solid appearance that I happen to prefer to classic Impressionism of the Monet-Passarro variety.
