Painter, printmaker and teacher, son of (1) Robert Walter Weir. His art education began in the studio of his father. There he and his half-brother (2) John Ferguson Weir acquired an appreciation for the Old Masters, particularly of the Italian Renaissance and of the 17th-century Dutch schools. While Weir pursued in his art a course very different from that of his father and half-brother, his personality as well as his artistic attitudes were shaped by them. In the winters of 1870-71 and 1871-2, he continued his studies at the National Academy of Design in New York, where his instructor was Lemuel Wilmarth (1835-1918).
