Nikolaus August Otto had quit his office…
1864 CE
Otto had served an apprenticeship in commerce and following his apprenticeship, had worked as a businessman in Frankfurt am Main and in Cologne before relocating to Cologne.
Eugen Langen, after an extensive technical training at the Polytechnic institute in Karlsruhe, has worked in his father's sugar factory, JJ Langen & Söhne, from 1857.
In 1864, he meets Otto, the son of a farmer: his father also runs the local post office.
The technically trained Langen recognizes the potential of Otto's development, and one month after the meeting, founds the first engine factory in the world, NA Otto & Cie.
