William Hyde Wollaston (1766-1828), an English chemist, invented the reflecting goniometer in 1809. This example probably belonged to Charles Nicoll Bancker (1777-1869), a Philadelphia insurance executive whose splendid collection of philosophical apparatus was purchased for the Stevens Institute of Technology. The “W. & S. JONES, Holborn, London” inscription refers to an instrument firm that was in business from 1791 to 1859.
