Harvey Thomas Dunn was an American painter and teacher. Dunn was born on a homestead farm near Manchester, South Dakota, in the county made famous by Laura Ingalls Wilder's descriptions of prairie life. The young man’s talent was first recognized by Ada Caldwell, an art instructor at South Dakota Agricultural College (now South Dakota State University), which Dunn attended in 1901-1902. Urged by Caldwell, Dunn pursued his artistic studies in Wilmington, Delaware, under the instruction of Howard Pyle. Dunn was one of a small group of Pyle's defining students who were to revolutionize the illustration world and today are collectively known as the Brandywine School.
