Brother and Sister (Mary and Gerald Thayer)

This double portrait of Thayer's two children, Mary and Gerald, is an intimate domestic work quite different from his idealized allegorical figures. Thayer was deeply devoted to his family and painted his children repeatedly, often giving them the angelic character of his symbolic figures while retaining their individual personalities. Gerald Thayer would later collaborate with his father on the camouflage book, sharing his scientific and artistic interests. The Smithsonian canvas shows the children in a moment of quiet togetherness, rendered with tender observation.

Thayer places the two children close together in soft, diffuse light characteristic of his figure work. The handling is warm and gentle, with the children's faces built through careful tonal observation that captures their youth and the specific relationship between the two.
