In 1904, Messrs. Dénes & Friedmann took over the representation of Bosch products in Italy, opening a sales office and workshop in Milan. Right from the start, the agency expanded rapidly and was taken over by Bosch in 1908. This phase of dynamic expansion was abruptly halted by the beginning of the First World War, as a consequence of which Bosch lost its agency in Milan. In 1919, however, the company succeeded in restarting business with its products.

From 1922 on, the Italian public limited company "Società Anomina per il commercio di materiali Robert Bosch" took over the distribution of an extended Bosch product range, and this under the management of Ludwig Winterberg, who had already been successful in managing the business before the war. Business expanded to such an extent that, in 1922 and 1923, separate sales offices could also be opened in Rome and Turin, and that in 1924 a new move by the Milan agency into an even bigger building became necessary. For Bosch, 1935 brought yet another expansion of its Italian business via its merger with the company Fabbrica Italiana Magneti Marelli. The two companies founded the sales company MABO S.A. in Milan, deciding to start up joint production and distribution of Bosch and Marelli products for Italy and its extensive North African colonies.

As a result of the Second World War, Bosch lost its agency in Italy for the second time. Bosch managed, however, by acquiring the company Scintilla AG, to establish itself in Italy again as early as 1947. Three years later, new licence and distribution agreements were signed between Bosch and MABO-Marelli. Finally, in 1959, Robert Bosch S.p.A. was re-established in Milan. As a result, the general agency for Bosch products in Italy passed from MABO to Robert Bosch S.p.A.
