Alfonso Cabeza de Vaca y Leighton, 11th Marquess of Portago, GE (11 October 1928 – 12 May 1957), best known as Alfonso de Portago, was a Spanish aristocrat, racing and bobsleigh driver, jockey and pilot. Born in London to a prominent family in the peerage of Spain, he was named after his godfather, king Alfonso XIII. His grandfather, the 9th Marquess of Portago had been Mayor of Madrid while his father, who was President of Puerta de Hierro and a prolific golfer, died of a heart attack while showering after a polo match. His mother, Olga Leighton, was an Irish nurse. At age 17, Portago began displaying his flamboyant lifestyle by winning a $500 bet after flying a borrowed plane under London Tower Bridge. He twice rode the Grand National as "gentleman rider" and formed the first Spanish bobsleigh team with his cousins, finishing 4th in the 1956 Winter Olympics, shaving the bronze medal by 0.14 seconds. In 1953, he was introduced into the Scuderia Ferrari team, competing at the Carrera Panamericana, 1000 km Buenos Aires and several Grand Prix, including a win and second place at the 1956 Tour de France Automobile and 1956 British Grand Prix respectively. His promising career was cut short in May 1957 after his renowned Ferrari 335 S crashed near the village of Guidizzolo when a tyre burst while driving along a dead straight road at 150mph at the Mille Miglia, killing both himself and his navigator and 9 spectators. The young age of the marquess who was 28 at the time of his death combined with his status as a sex symbol caused a shock amongst many, having several tributes and landmarks named after him, most notably the "Portago curve" at Jarama racetrack. The Marquess of Portago was seen by many as a true playboy of his time; "a tall, handsome and wealthy Spanish aristocrat who captured everybody's imagination". Gregor Grant famously said of him: "a man like Portago appears only once in a generation, and it would probably be more accurate to say only once in a lifetime. The fellow does everything fabulously well. Never mind the driving, the steeplechasing, the bobsledding, the athletic side of things, never mind being fluent in 4 languages. (...) He could be the best bridge player in the world if he cared to try, he could certainly be a great soldier, and I suspect he could
