Piero Ferrari is the son of
Enzo Ferrari (20 February 1898 – 14 August 1988) and his mistress, Lina Lardi (1911–2006). He is also the younger half-brother of
Dino Ferrari (1932–1956). Dino had been diagnosed with
Duchenne muscular dystrophy, and died at the age of 24. Piero never met his older brother, despite being 11 years old at the time of Dino's death. After Dino's death, Enzo made Piero one of his principal heirs, giving him a 10% stake in the
Ferrari company. Enzo had met Lina Lardi in the late 1930s, when she was working at Carrozzerie Orlandi, a coachbuilder company in Modena. The two began a romantic affair soon after; their son, Piero, was born on 22 May 1945; and Enzo and Lina continued their relationship until Ferrari's death in 1988. As divorce was illegal in Italy until 1975, Piero could not be acknowledged as a Ferrari family member until the death of Enzo's estranged wife, Laura, on 27 February 1978. In 1990, he legally changed his name from Piero Lardi Ferrari to Piero Ferrari. Ferrari grew up in Modena. He became passionate about mechanics by hanging out in a bike repair shop close to his mother's home. In 1964, he obtained a high school diploma with the mechanics course of the Fermo Corni Technical Institute in Modena, an
istituto tecnico industriale. ==Career at Ferrari==
