to his death: The death of Alfredo took a toll on his parents' marriage. His mother, Laura Dominica Garello, never got over the loss of her only son, and her behaviour became increasingly erratic and unstable. Piero Ferrari, Dino's younger half-brother who was born out-of-wedlock to Enzo Ferrari and mistress Lina Lardi on 22 May 1945, and who became Enzo's heir after Dino's death, has stated: "I never knew Dino, but I have never felt I was a victim of his memory, or of the pain that my father, Enzo, had always felt because of his death. And I would not be sincere if I did not say that when I was recognized [in 1978, after Laura's death], I experienced a great deal of emotion." Gino Rancati, a long-time friend of Dino's and Piero's father, Enzo Ferrari, said: "Piero is now a man, with a family of his own, but his father [Enzo]'s obsession with Dino's memory must have left a mark on him." Legacy Dino Ferrari is probably best-known posthumously for designing the Ferrari Dino engine, a series of V6s and V8s that were produced by Ferrari from the late 1950s into the early 2000s; and the Dino, a marque best known for mid-engined, rear-drive sports cars produced by Ferrari from 1957 to 1976. The marque came into existence in late 1956, with a front-engined Formula Two racer powered by a brand new Ferrari Dino V6 engine. The name "Dino" was also used for some models with engines smaller than 12 cylinders, it was an attempt by the company to offer a relatively low-cost sports car. The Ferrari name remained reserved for its premium V12 and flat-12 models until 1976, when "Dino" was retired in favor of full Ferrari branding. Alongside engineer Vittorio Jano, Dino persuaded his father, Enzo Ferrari, to produce a line of racing cars in the 1950s with V6 and V8 engines. The script that adorns the badge and cylinder head covers was based on Dino's own signature. In 1962, Enzo Ferrari launched the Premio Giornalistico Dino Ferrari (the Dino Ferrari Prize for Journalism) in memory of his son, originally with a prize of 500,000 lira. The prize money was later increased to 1 million lira, in a addition to a small bronze statuette of the Ferrari emblem, the Prancing Horse. Writers Gino Rancati, Giovanni Arpino, and Alberto Bevilacqua, among others, have been recipients of this
