Robert Koch founded his namesake in Frankfurt, Germany in 1879.  His reputation for quality and craftsmanship allowed him to become the jeweler for the court in 1883.  The royal appointment attracted more attention and a second strategic placement of a store in the spa resort of Baden Baden drew the attention of more royalty such as the King of Italy, the Russian Tsar, and even the Prince of Wales.  In 1902, Robert Koch passed away, leaving Louis in charge.  Louis successfully managed the firm for nearly half a century.  The family lost control during the second world war when it was "aryanized" by the Nazi regime.  The company eventually dissolved without the expertise of the founding family.
