Musical machine by HohlefeldFather Drais is appointed president of the Upper Court transferred to Mannheim and buys a house there (destroyed in World War II, commemorative plaque on the new building in M1, 8). Karl Drais joins later and presumably works as a teacher at the private commercial college of professor Buermann whom he had gotten to know at the university of Heidelberg. He can publish his ideas in the Badisches Magazin, an apolitical newspaper (political ones were forbidden by Napoleon). He builds a piano recorder that automatically writes improvisations directly as strokes instead of notes on paper and also records volume in contrast to the machine by Hohlefeld.
