Ferruccio Lamborghini was an Italian industrialist who is best recognized as the founder of the high-end sports cars company Automobili Lamborghini in Sant'Agata Bolognese, northern Italy. The son of grape farmers, he tinkered with machinery in his youth and studied mechanics in college, following which he served as a vehicle maintenance supervisor during the Second World War. He subsequently established a garage which eventually turned into the tractor manufacturing business Lamborghini Trattori. Apart from these two vehicle businesses, he also founded Lamborghini Bruciatori, an oil heater factory which later became, Lamborghini Calor, which also produced air conditioners, and Lamborghini Oleodinamica, a hydraulic valves and equipment manufacturing company. While he is best known for the luxury car business, it is said that he was prompted to become a car manufacturer after he was insulted by racer and businessman Enzo Ferrari, founder of the Ferrari car brand, when he had approached the latter with his complaints about Ferrari's after sales service.
