                      -     DetailsRelatedObject Details- Willard, Jr., Aaron
- Description
- Like many instruments of the sort made in London, this American one could be used as an orrery (Sun and planets out to Saturn) or a tellurian (Sun, Earth and Moon), with the mechanisms moved by a crank with an ivory handle. Four elegant brass legs support a mahogany horizon circle. The printed paper label covering this circle is marked “MADE-BY / Aaron Willard Jr. / BOSTON.” The one brass Sun can be used with either form. The planets are ivory. The plate of the tellurian mechanism is marked “A. WILLARD JR. BOSTON.”
- Aaron Willard Jr. (1783-1864) was a productive and prosperous clockmaker in Boston who apprenticed with his father and took over the business in 1823. He probably made this instrument in collaboration with John Locke (1792-1856), a graduate of the Yale Medical School who settled in Cincinnati. Locke also established a school for young ladies, developed an electro-chronograph for the U.S. Naval Observatory, and made important contributions to American geology.
