Roland Walter Ratzenberger (4 July 1960 – 30 April 1994) was an Austrian racing driver, who competed in Formula One at three Grands Prix in 1994. Born and raised in Salzburg, Ratzenberger began his racing career as a protégé of Walter Lechner, joining the Lechner Racing School at the Salzburg ring upon graduating from technical school, aged 18. Ratzenberger progressed to Formula Ford in 1983, winning multiple national and continental titles, as well as the festival in 1986. Ratzenberger balanced his next two seasons between touring car racing and Formula Three; he contested the World Touring Car Championship in 1987 with Schnitzer, achieving four podium finishes in 10 races whilst driving the BMW E30 M3. After finishing third in the 1989 British Formula 3000 Championship and retiring from his 24 Hours of Le Mans debut, Ratzenberger moved into Japanese motorsport with Toyota. Amongst competing in World Sportscar, All-Japan Sports Prototype, Japanese Touring Car and Japanese Formula 3000, Ratzenberger also entered four further editions of Le Mans from 1990 to 1993, winning the C2 class at the latter in the Toyota 93C-V with SARD.
