content: Milton Bradley (1836-1911) established the Milton Bradley Co. in Springfield, Mass., in 1860, and achieved financial success with “The Checkered Game of Life,” a board game introduced in 1861. Always interested in education, Bradley published Edward Wiebe, <i>Paradise of Childhood</i> (1869), the first book in English based on the ideas of the German educator, Friedrich Froebel. He also published <i>Color in the School-Room</i> (1890), <i>Color in the Kindergarten</i> (1893), and <i>Elementary Color</i> (1895). And, along with crayons and colored papers, he sold color disks and wheels based on the fundamental work of the British scientist, James Clerk Maxwell.
label: Description
content: This is an example of the color wheel for which Bradley received a patent in 1893. The Smithsonian bought it in 1898, at the same time that Bradley became a consultant to a Smithsonian committee formed to consider a revised system of naming colors for scientific purposes. The box accompanying the wheel is marked: “MAXWELL DISKS FOR USE WITH THE Bradley Color Wheel, For Primary Education” and “MILTON BRADLEY CO., Springfield, Mass.”
