Aldo Andretti
Aldo Andretti (born February 28, 1940 in Montona d'Istria, Italy (now Motovun, Croatia)) is the twin brother of Mario Andretti and the father of John Andretti and Adam Andretti. He is the uncle of Michael Andretti and Jeff Andretti, and great-uncle to Marco Andretti.
Aldo and Mario were born in Italy, where they were inspired by watching the great Alberto Ascari race at Monza. They emigrated with their family to the United States at the age of 14. The family settled in Nazareth, Pennsylvania and the brothers discovered racing on an oval track in their home town.
Together they rebuilt an old Hudson into a stock car and began racing, and immediately began winning. They took turns in the car and both demonstrated great talent.
However, Aldo suffered severe damage to an arm in a sprint car crash in 1959, and eventually quit racing, while Mario went on to win the Indianapolis 500, the Daytona 500, and the Formula One World Championship.
