Kottmann

The Kottmann family of Solothurn founded the Langendorf Watch Company factory in Langendorf in the 1870s. This grew to be the largest watch factory in Switzerland by the turn of the 20th century and was a major watch producer for decades. The company was run by four generations of the Kottmann family: Johann, Charles, Ernst and Rudolf, and Hans and Guido. It was sold to SSIH following the sudden deaths of the latter two in 1964 and 1965. Despite this watchmaking success, the Kottmann family was better-known as influential medical doctors, pioneering surgeries and serving in government.
