Charles Achilles Spencer was the first successful American maker of microscopes, publishing his first catalogue in 1838.  Later, in 1865, he began operating as C.A. Spencer & Sons.  In 1873 Spencer and his sons moved from the original shop in Canastota, New York to Geneva, New York. After Charles death in 1881 the business was carried on by his son Herbert, who, after a time moved to Cleveland, Ohio, and then, in 1890, to Buffalo, New York, where the company remained. Between 1890 and 1895 the company operated by the name of Spencer & Smith. The Spencer Company was incorporated in 1895, using the name Spencer Lens Company up into the 1940's. American Optical bought the Spencer Lens Company in 1935 and by 1945 it was known as the Instrument Division of American Optical Company (hence the designation found on many microscopes as ‘AO Spencer’). In 1982 Reichert partnered with AO, by that time a part of the Warner-Lambert Group. The partnership used the name Reichert-Jung. They were bought by Cambridge Instruments in 1986, which then purchased Bausch & Lomb's optical systems division in 1987, using the name Cambridge instruments. Cambridge Instruments merged with Wild-Leitz in 1990 to form Leica plc. Microscope 132 was made by the Spencer Lens Company and should be dated to the 1930s. The instrument contains the inscription ‘Spencer, Buffalo, USA’ and is identified as ‘Dissecting microscope No. 82’ in the 1929 firm’s catalogue (Figure 1).
