Jo Siffert, affectionately known as 'Seppi' to his family and friends, was a prominent Swiss racing driver born on July 7, 1936, in Fribourg. He began his illustrious career in motorsport on two wheels, clinching the Swiss 350 cc motorcycle championship in 1959. His passion for speed soon transitioned to four wheels, where he made his debut in Formula Junior with a Stanguellini.
In 1962, Siffert entered the world of Formula One as a privateer, driving a four-cylinder Lotus-Climax. His journey through the racing circuit saw him join the Swiss team Scuderia Filipinetti and later the renowned Rob Walker Racing Team in 1964. Siffert's early career was marked by notable victories in the Mediterranean Grands Prix in 1964 and 1965, where he narrowly outpaced the legendary Jim Clark.
Throughout his ten seasons in Formula One, Siffert achieved remarkable success, winning two World Championship races—one with the Rob Walker Racing Team and another with BRM. His career, however, was tragically cut short when he lost his life during the 1971 World Championship Victory Race due to a mechanical failure that led to a devastating crash.
In his personal life, Siffert was married twice, with his second marriage to Simone beginning during the peak of his racing career in the late 1960s. Together, they welcomed two children, Véronique and Philippe, who carry on his legacy.
