Edouard Koehn (1839-1908) He was born in Germany and studied at the horological school of Geneva. He began as a simple repairman with Patek Philippe and became a partner. In 1891 Edouard Koehn bought the company of H.R. Ekegren. The level of quality awareness he adopted during his many years with Patek Philippe is reflected later in his own designs and works.
