Stefan Bellof

Born in Gießen, West Germany, Bellof made his karting début in 1973, following in his brother Georg's footsteps and competing in the Automobilclub von Deutschland's Federal Junior Cup, where he finished fourth. Several other top-five championship placings followed before he won the International Karting Championship of Luxembourg in 1976. That same year he finished thirteenth in the Karting World Championship in Hagen, Germany. Georg won the German Karting Championship in 1978, while Stefan finished eighth, improving to third in 1979 and becoming German champion in 1980.

Bellof moved into Formula Ford at the tail end of the 1979 season as a member of Walter Lechner's Racing School setup, making his bow at Hockenheim in November 1979, where he finished second. A full season in the 1600cc class followed in 1980, and Bellof became champion taking eight victories and nine podium placings from twelve races. He continued in the series in 1981, taking five wins, and also made forays into the 2000cc class, retiring from both starts in the Lion Trophy at Zolder and the 300 km at the Nürburgring. He also contested three VW Castrol Europa Pokal races, winning one.

Bellof moved into the German Formula Three Championship in 1981, debuting for Bertram Schäfer's team at Wunstorf. Despite missing the opening two races, he led the championship by seven points going into the final round at the Nürburgring, having taken a top-four finish in each of his first eight races. He finished thirteenth in the final race, while title rivals Frank Jelinski and Franz Konrad finished first and second to overhaul his points total. Eleven points separated Bellof from Jelinski, who claimed his second successive German Formula Three championship. At the conclusion of the season, Bellof contested the Formula Ford Festival at Brands Hatch, but was excluded after finishing sixth in his quarter-final heat for excessive contact.

Bellof joined Mike Thackwell and Alain Ferté at a test session with Maurer Motorsport at Circuit Paul Ricard at the end of 1981. Eje Elgh, who had finished third with Maurer in the 1981 European Formula Two Championship, was impressed by Bellof and recommended him to team boss Willy Maurer, who eventually signed an eight-year management deal with Bellof.

The first race of the 1982 season was the BRDC International Trophy at Silverstone, where Bellof drove through the field in showery conditions to win by 21 seconds ahead of Satoru Nakajima, becoming the first driver to win outright on his European Formula Two début after Dave Morgan won on aggregate at Silverstone in 1972. He followed this with a victory at the Jim Clark Gedächtnisrennen at Hockenheim from pole position, also setting the fastest lap. Two points from the next six races left him fourth in the championship with 33 points.

His 1983 Formula Two season was less successful, with only one podium — second at Jarama — along with a disqualification from third at the Pau Grand Prix after his and Ferté's cars were found to be underweight. He finished ninth on nine points.

While competing in Formula Two in 1982, Bellof made a one-off appearance in the World Endurance Championship at the 1000 km of Spa, partnering Rolf Stommelen in a Kremer CK5. The pairing retired on lap 51 with a starter motor problem. The previous weekend he had joined Kremer for the Hessen Cup at Hockenheim in the Deutsche Rennsport Meisterschaft, retiring with transmission failure.

In 1983, Bellof joined the Rothmans-backed Porsche factory team for the World Endurance Championship, driving a Porsche 956 alongside Derek Bell. Bellof and Bell won their first race together at the 1000 km Silverstone, beating Bob Wollek and Stefan Johansson by almost a minute at an average speed of 198.274 kilometres per hour. Bellof's pole time for the race — 1 minute 13.15 seconds — would have put him twelfth on the grid for the British Grand Prix later that year.

At the 1000 km Nürburgring, Bellof set a pole time of 6 minutes 11.13 seconds — the fastest lap ever driven on the Nordschleife in its current configuration — taking pole by five seconds at an average speed of 202.073 kilometres per hour. He also set the fastest lap during the race at 6 minutes 25.91 seconds, which remains the official Nordschleife lap record for all cars. Two laps after setting the race record, on lap 20, his 956 — chassis 956-007 — flipped out at the Pflanzgarten. Bellof added two more wins later in the season at Kyalami and Fuji, ending the season fourth in the championship. He also won the non-championship Norisring Trophäe race.

Bellof was the dominant force in the 1984 championship alongside Bell, with John Watson also joining the team. He also contested races with Brun Motorsport, winning at Imola partnering Hans-Joachim Stuck. Bell and Bellof won the opening round at Monza after being initially disqualified in scrutineering — their 956 was found to be under the 850 kg weight limit, as was the third-placed Martini Racing Lancia LC2. Both teams successfully appealed and were reinstated. Further victories at the Nürburgring, Spa, Mosport and Sandown helped Bellof claim the World Sportscar title by eight points from Jochen Mass, and helped Porsche secure the manufacturer's title. He was also champion in the German DRM series. In 1985, Bellof contested six sportscar races, taking one win at the Norisring alongside Thierry Boutsen in DRM.

Bellof first tested a Formula One car towards the end of 1983, when he joined Ayrton Senna and Martin Brundle in testing for McLaren at Silverstone, where Bellof damaged the gearbox before Brundle's opportunity. He moved into Formula One ahead of the 1984 season, joining Tyrrell Racing Organisation to partner Brundle in naturally aspirated Ford-engined machinery giving away in excess of 150 horsepower to their turbo rivals.

Bellof failed to finish in his first two races in Brazil and South Africa, before scoring his first two championship points in successive races at Zolder and Imola. A retirement followed at Dijon, before he achieved a podium in the rain-shortened Monaco Grand Prix, starting from 20th and last place. He was catching race-leaders Alain Prost and Senna when the race was curtailed after 31 laps; at the finish, Bellof was 21 seconds behind Prost and 13.7 behind Senna. Retirements followed in Canada and Detroit, where Brundle claimed the team's best result of the season with second place.

Bellof, Brundle and Tyrrell were stripped of all their 1984 championship points after a dispute over lead ballast in their fuel tanks found after the Detroit Grand Prix. FISA charged the team on four separate counts; the FIA Court of Appeal ultimately rejected the team's final appeal and removed them from the remainder of the season.

Bellof remained with Tyrrell into 1985, missing the opening Brazilian Grand Prix while Brundle and Stefan Johansson started in Rio. He returned at the Portuguese Grand Prix at Estoril, again in wet conditions similar to Monaco 1984, starting 21st and finishing in the top six for a point. He failed to qualify at Monaco — the only time he failed to qualify in his Formula One career, along with his exclusion at the 1984 Austrian Grand Prix. He made amends for his 1984 Detroit error by finishing fourth in the 1985 race, which would be his final three points in Formula One. His final race was the Dutch Grand Prix, where his Renault turbocharged engine failed on lap 40. Tyrrell had only changed to such engines from the German Grand Prix onwards, meaning Bellof never had a full opportunity to show his talent at the wheel of a Formula One car.

Bellof was racing at the 1985 1000 km of Spa at Spa-Francorchamps on 1 September 1985, the seventh race of the season. Partnering Thierry Boutsen as he had done in his other 1985 appearances, their Brun-Porsche 956B-116 started from third on the grid, 0.86 seconds adrift of the pole-winning Lancia LC2.

On lap 78, Bellof was racing Jacky Ickx's works Porsche 962C from the La Source hairpin towards Eau Rouge. Both drivers had just commenced their stints after Boutsen and Jochen Mass started them. Entering the left kink of Eau Rouge, Bellof moved left of Ickx to set up a pass for the Raidillon. This created a side draft on Ickx's 962C, which pulled left, bringing Bellof's right front into contact with Ickx's left rear, sending both cars into the barriers. Ickx's car spun into the barrier rear-first, which likely saved his life; Bellof crashed directly into the barriers at unabated speed with his left front corner. The Brun Porsche caught fire; Ickx climbed unaided from his car and attempted to help safety workers. The emergency medical team struggled for over ten minutes before extricating Bellof. He was pronounced dead of massive internal injuries at the track hospital. Out of respect, the race organisers ended the event approximately 150 km earlier than planned.

The entire incident was recorded on an in-car camera in Ickx's 962C. Bellof's accident was the second in three weeks in which a driver was killed in a Porsche: at the previous World Sportscar race at Mosport Park, fellow West German F1 driver Manfred Winkelhock had died of severe head trauma after crashing into a concrete wall while in a Kremer Racing-run Porsche 962C.

After Bellof's death, Formula One teams became unwilling to allow their drivers to compete outside the championship. Fellow Formula One driver Jonathan Palmer was injured in an unrelated accident at the same meeting, resulting in many teams tightening contracts to prohibit drivers from competing in other championships. Bellof's talent had attracted an offer from Ferrari for the 1986 season, with a meeting scheduled with Enzo Ferrari before his death.

Bellof is often mentioned as Michael Schumacher's childhood racing idol. In 2010, his family donated his racing mementos — including his go-kart, racing overalls, helmets from his Porsche and Tyrrell days, and trophies — to the Sammler und Hobbywelt museum for public display. A karting circuit named Motorsportarena Stefan Bellof is located in Oppenrod. In August 2013, management of the Nürburgring renamed the section of the Nordschleife previously known as Pflanzgarten III as the Stefan-Bellof-S. In 2015, Timo Bernhard wore a helmet with Bellof's livery at the 6 Hours of Spa-Francorchamps to commemorate the 30th anniversary of his death. In 2009, a poll of 217 Formula One drivers by British magazine Autosport ranked Bellof as their 35th greatest Formula One driver.
