After completing his apprenticeship he attended an engineering school in Esslingen. In 1924 he started work for Mauser in Oberndorf as an engineer and stayed with them until 1931. After the fall of Germany to the Allied Forces at the end of World World War II the Mauser factory was dismantled.
Koch, Edmund Heckler and Alex Seidel saved what they could and used it to found Heckler & Koch.
