In 1833 Connecticut school reformer and lecturer Josiah Holbrook developed a collection of apparatus for teaching in homes and schools. These models (above, right) are part of Holbrook’s set. He designed them to help students learn the names of simple solids, basic rules for calculating the area of various flat surfaces, and elementary drawing. Holbrook advertised that his equipment was “Good enough for the best, and cheap enough for the poorest.” It was used in thousands of schools. |
