Born in Cuba Chimeri came from an Italian family which settled in Venezuela. He raced in the 1960 Argentine Grand Prix in his tatty, ill-prepared Maserati 250F, failing to finish the race. Two weeks later he was killed practicing for the Gran Premio Libertad at the Camp Freedom military airfield near Havana. His Ferrari crashed through hay bales and a protective steel barrier and plunged 150 feet into a ravine. Amazingly he was still alive and he was flown to hospital by helicopter but he died there later that afternoon.
