Piercarlo Ghinzani
Fondmetal first appeared in Formula One in 1983 as a sponsor for Italian driver Piercarlo Ghinzani. In the mid-1980s, the company supplied wheels to Williams, Tyrrell and Ligier, while continuing to sponsor Ghinzani and, later, the Osella team. In 1989, Fondmetal became Osella's major sponsor, and by 1990 Rumi had become the team's majority shareholder. At the end of that year, he decided to take over the whole operation.
