Frederik Jansen van Vuuren (c. 1957/58 – 5 March 1977) was a race marshal at the 1977 South African Grand Prix, who was responsible for Tom Pryce's death as well as his own. Going into the race, Van Vuuren was a young 19-year-old fan of Formula One who volunteered successfully to be a marshal at the South African GP for the first time. Some blamed Zorzi for the accident, because it would have been safer had he pulled off into the pits to retire rather than stay out on track.
