WILLIAM NEWTON BARTHOLOMEW
William N. Bartholomew (1822 - 1898) was a painter and a teacher of drawing and painting in the Boston public schools. In the 1860s he published a series of textbooks on art education. His method was to present a series of sketches which students could copy, thereby learning to draw.
Bartholomew came frequently to Post Mills in the summers, and painted there. He also spent time in Grafton, VT, and the historical society there is said to have several of his paintings.
