Edward Bausch added the manufacture of microscopes to the company's product line, and by 1900, the company was making microscopes and accessories, slide and opaque projectors, photographic lenses and prism binoculars-but no surveying or engineering instruments. That changed in 1905 when George N. Saegmuller moved his company from Washington, D. Bausch & Lomb - Microscope Makers J.J. Bausch was born in Germany, in 1830, and emigrated to America in 1849. Henry Lomb, born in Germany in 1828, also emigrated to America in the same year. Meeting in Rochester, NY, these two men started a spectacle making business, and, in 1866, started the Vulcanite Optical Instrument Co., to make hard.

George N. Saegmuller moved the business of Fauth & Co., G. N. Saegmuller, Prop. from Washington, D. C. to Rochester, New York in May 1905, opening in Rochester in June 1905. The new company, Bausch, Lomb, Saegmuller, apparently continued using the same serial number sequence as had been employed at Fauth & Co., with a transfer of name somewhere between serial number 2,400 and 2,600. The serial number transition between Bausch, Lomb, Saegmuller and the Triple Alliance instruments, which took place on January 1, 1908, took place at about serial number 6,750, although it seems extremely doubtful that Bausch, Lomb, Saegmuller produced more than 4,000 instruments in two and a half years. No explanation can be given for this disparity at this time, unless Bausch, Lomb, Saegmuller also numbered all its military output with its serial numbers. (Later military production used different serial numbers.)

Bausch Lomb Serial Numbers Microscope Diagram

The highest recorded serial number on a Bausch & Lomb surveying instrument is just over 12,000 on an instrument owned by Bausch & Lomb. If Bausch & Lomb manufactured instruments under its own name for a ten year period, the output would be approximately 550 instruments per year, but it must be noted that some instruments have two serial numbers. For example, the trough compasses on Bausch & Lomb's plane table alidades are also serial numbered. As a result, it's most probably fair to say that Bausch & Lomb's output averaged about 400-500 instruments per year. ~Thomas Garver
