Diatto

Diatto was an Italian manufacturing company founded in 1835 in Turin by Guglielmo Diatto (1804–1864) to make 'carriages for wealthy customers'. In 1874 Guglielmo’s sons, Giovanni and Battista Diatto, began building railway carriages for Compagnie Internationale des Wagons-Lits and the Orient Express. In 1905 Guglielmo's grandsons, Vittorio and Pietro Diatto, began Diatto-Clément, a cooperative venture making motor-vehicles under license from French manufacturer Clément-Bayard owned by industrialist Adolphe Clément-Bayard. By 1909 they had full ownership of 'Autocostruzioni Diatto' and began developing their own motor-vehicles and exporting them worldwide.
