I hope this helps, I found it interesting also.
Alfredo Ferrari, called Dino (from Alfredino, = little Alfredo) was brilliant since he was a little kid. When he was a child he used to follow his father into the Maranello factory and watch what of exciting and interesting was happening there. He began to love that yellow shield in the red background and understand that everything there, was part of him. The most fantastic thing for his child's eyes were the engines. A mysterious steal box with such a power inside to explode, like his young little heart. Maybe there was an unconscious link between his disease and his natural genius for projecting engines.
He was suffering of a terrible disease that paralyzes the external mechanisms of the body, that paralyzes the power of the movements, while the heart's power inside is high and alive.
Some people said that Dino was a rare genius, cleverer than his father too. Probably he would be an engine projectionist only but for sure his talent would project something of important if he would have the chance to do it.
One day the 11 years old Dino went to Maranello with his father. There was an engine on a test bank. They approached to it and Enzo began to talk with a mechanic while the Dino's eyes were more and more opened wide between the surprised and the excited. The young boy took a corner of the Enzo's jacket and pulled it: "Papà [daddy], one day I'll build one by myself too, isn't it?".

Enzo Ferrari was so happy that stood in silence for the surprise and a little tear dropped down by his cheek.
1956 was one of the most important years of the Enzo Ferrari's life. In Fact in that year the Maranello factory began to increase its car production going from 81 to 113 cars produced. The reason of this success (in 1961 Ferrari would have produced 1246 cars!) was the fact of a sure and reliable production system and the effort of turinese chassis designer Pininfarina.
1956 reserved to Enzo Ferrari a big pain too.The biggest. Dino died in their Modena home on 30th June 1956. His body after a short fever "stopped to work" turning off slowly, like a consumpted engine. The day after, in the French Grand Prix, Peter Collins won running with a black string on his arm and said "Mister Enzo, this is a gift for you and a dedication to Dino". Enzo Ferrari never forgot this "gift".
That's why for years and years Enzo Ferrari always wore a black tie, meaning the deep and never ending pain for his only one son so loved and too soon lost.(later Enzo Ferrari would have another son with another woman than his wife: Piero Lardi Ferrari, actual honorary president of the Ferrari company).
Enzo remembered Dino in many ways. Titling the Imola track (near Maranello) to him ("Circuito Dino Ferrari"), and that engine: the one that Dino was projecting for F1, a V6, a full Dino's idea and ended by Vittorio Jano. The cars powered by that engine model were all called "Dino", like the Dino 246 F1 that became world champion driven by Mike Hawthorn in 1958.
