During the practice session for the 1977 South African Grand Prix, run in wet conditions, Pryce was faster than everyone, including world champion drivers Niki Lauda and James Hunt.

During the race, he collided at high speed with a safety marshal, Frederik Jansen van Vuuren, and both men were killed.

[3] Pryce's older brother, David, died at the age of three leaving Tom an only child for much of the time he was growing up, although his parents did foster a young girl called Sandra for a while.

[5] Pryce took an interest in cars while driving a baker's van at the age of 10, before informing his parents that he wanted to be a racing driver.

[11] Pryce soon abandoned his farming career and moved to a guest house in West Kingsdown, near the Brands Hatch circuit.

[12] Pryce continued to make a name for himself during 1971, entering a new twin-seater Sportscar category called Formula F100, which he won with what was described by motorsports author David Tremayne as "embarrassing ease".

His best result for the team came at the Norisring where he was leading the race until a brake failure meant he had to give up first place to teammate Tim Schenken.

Jack Pryce recalled that his son did not want to win the award, as he thought it was "a jinx on a driver's career".

[21] Pryce made his début for the team at the BRDC International Trophy, a non-championship Formula One event held at Silverstone, but lack of an airbox and an engine cover, along with his shortage of experience in the car, made him the slowest driver of the 16 competitors during qualifying: 26 seconds slower than James Hunt's Hesketh in pole position.

Pryce's World Championship début came at the 1974 Belgian Grand Prix, where he qualified in 20th place, 3 seconds slower than the fastest time set by Clay Regazzoni.

Pryce retired on the first lap of the race after a collision with James Hunt at the first corner broke his Shadow DN3's rear suspension.

Later in the season, Pryce received 100 bottles of champagne for finishing fastest in the practice session for the British Grand Prix at Brands Hatch.

His season ended with an engine failure in Canada, and the Shadow severely off the pace at Watkins Glen in the United States.

At the end of the season Pryce was equal 18th in the Drivers' Championship with veteran Graham Hill and Vittorio Brambilla.

Rumour linked him with a drive at Lotus, the team run by Colin Chapman, who had been keeping an eye on Pryce's progress throughout 1973 and 1974.

[38] Pryce showed other signs of promise during the season, most notably in Monaco and Silverstone where he qualified on the front row of the grid, the latter being in pole position.

The highest of those came in Germany where he finished fourth, despite the fact that while he was running second behind Carlos Reutemann fuel had been leaking into the cockpit of his DN5 during the final laps around the Nürburgring, reportedly "searing his skin and almost blinding him with fumes".

[40] The Welshman later received the Prix Rouge et Blanc Jo Siffert award, named after the Swiss Formula One driver, for this achievement.

[43] Once the 1976 Formula One World Championship season got under way Pryce instantly added a second podium finish to his tally, at the first round in Brazil.

This came at the expense of continuing teammate Jarier, who was caught out by oil on the track from James Hunt's McLaren.

[45] Rumors that Pryce would run as Mario Andretti's teammate for the Lotus team in 1978 were strong, as it coincided with the end of his contract with Shadow.

[48] Tom Pryce began his final race weekend, the 1977 South African Grand Prix at Kyalami, by setting the fastest time in the Wednesday practice session, held in wet weather.

The weather dried up prior to the Thursday session, and he slipped back down the grid to fifteenth place, almost two seconds slower than James Hunt's pole position time.

The first marshal to cross the track was a 25-year-old panel beater named Bill, and the second was 19-year-old Frederik "Frikkie" Jansen van Vuuren, who was carrying a 40-pound (18 kg) fire extinguisher.

Stuck saw Jansen van Vuuren and moved to the right to avoid both marshals, missing Bill by what Tremayne calls "millimetres".

[56] The eventual race winner was Austrian Niki Lauda, his first win since his near fatal accident during the 1976 German Grand Prix.

[51] Pryce's death was met with great grief from all those who knew him, especially his wife Nella, his parents Jack and Gwyneth and the Shadow team.

[59] During its re-design, the Anglesey Circuit in North Wales named the Tom Pryce Straight after a request from Ruthin Town Council.

Eddie Knipe, a South African living in Sevenoaks, sought permission from Nella Pryce to approach the Ruthin Town Council to commemorate her late husband.

Neil Dalrymple, a local artist, was commissioned by Ruthin Town Council in 2008 to design an 8-by-4-foot (2.4 by 1.2 m) plaque and in February 2009, an auction of Formula One pit passes to fund its manufacture was announced.
