- Description
- Albert Ott was a precision instrument maker who began in business in Kempton, a small town in Bavaria, in 1880, and was later joined by his sons, Herman and Ludwig. Over the years, the Otts collaborated with many distinguished European hydraulic engineers. This example, which dates from around 1917, is marked with the Ott monogram. The additional “Keuffel & Essser, Co., New York, No. 2237” signature refers to the firm that imported these instruments into the United States. The National Bureau of Standards, the organization that calibrated current meters for federal agencies and engineers in private practice, transferred it to the Smithsonian in 1959.
