In 1925, Max, barely of age, founded UNDA RADIO, one of the first radio factories in Italy, and the following year he married Trude, whom he had met in high school in Bolzano. She was the daughter of a lawyer, musician, historian and congressman in the Italian parliament, offspring of the antique Bolzano family Walther von Herbstenburg. The factory building, adjacent to the villa, still exists, albeit restructured. Meanwhile the family grew with the births of Heini, Hans, Lisa.
