Hawley C. White (1848-1925), a photographer in Bennington, Vt., patented a stereoscope viewer in 1895, and termed it a Perfecscope. The H. C. White Co. manufactured stereoscopes of this sort, and applied for a trademark on the term in 1899. This example is made of aluminum. An inscription reads, in part, “THE PERFECSCOPE / TRADE MARK / . . .” It was probably used for experiments in experimental psychology.
