Saegmuller

George Nicholas Saegmuller (1847–1934) was born in Bavaria and educated at the Polytechnic School in Nuremberg. He moved to England in 1865 to work as a draftsman for Thomas Cooke & Sons. In 1870, after serving a brief stint in the German army, Saegmuller moved to Washington, D.C., to work for William Würdemann. He became chief of the Instrument Shop of the United States Coast Survey in 1874. That same year he joined with his brothers-in-law, Camill Fauth and Henry Lockwood, to form Fauth & Co. In 1887, when Fauth retired, Saegmuller became manager and sole proprietor of the firm. Although Saegmuller began trading under his own name in 1892, offering "All kinds of Fixed and Portable Astronomical and the higher grades of engineering Instruments," he continued labeling his instruments Fauth until 1905, when he moved to Rochester, N.Y., and allied himself with Bausch & Lomb.

In 1879 Saegmuller obtained a patent (#212,405) for a quick-leveling tripod head for use with any transit or leveling instrument. In 1881 he obtained a patent (#240,849) for a solar attachment that fit onto a standard surveyor’s transit and enabled the observer to determine the astronomical meridian in an expeditious manner. In later life Saegmuller developed fire control instruments and other apparatus for the United States Navy.
