Baconin Borzacchini (Terni 28 September 1898 – Monza 10 September 1933) was an Italian Grand Prix motor racing driver often referred to as Mario Umberto Borzacchini. Biography Born Baconino Francesco Domenico Borzacchini in Terni in the Umbria region of Italy, at age 14 he began working in a garage, training as a repairman. After service in the army during World War I, he began racing motorcycles before turning to automobile competitions in 1926. During the next two years he won six Italian hillclimbing events driving a Salmson. He earned victories at three significant Italian races including the Etna Cup at Catania and the 1100cc class at the 1926 and 1927 Targa Florio where he beat fellow up-and-comer Luigi Fagioli. Borzacchini's success ultimately led to an offer to join the Maserati racing team and driving for them, he won the 1927 Terni-Passo della Somma and the Coppa della Collina Pistoiese."

In 1931 he signed to drive Alfa Romeos for Scuderia Ferrari where he became a great friend of team-mate Tazio Nuvolari. Although he won the Circuito di Avellino, Borzacchini's season was dogged by both bad luck and the brilliance of Nuvolari.
