I think that might be lorenzo Bandini, he died at Monaco.
I suppose these sort of images do drive home just how dangerous the sport used to be, many current motor sport fans have grown to know the sport as it has been for the last decade or so, Ie incredibly well run and uncannily safe.
It wasn't always the case, when the above mentioned Stewart crashed heavily at Spa, he was in the car for about half an hour or more before other drivers found him (almost by accident) borrowed some tools off a spectator and took what was left of his BRM to bits around him. They then had to call an ambulance to take him to a hospital, but only after he had been left on the floor of a so called medical centre for while. The Ambulance then got lost on the way to the Hospital.
Stewart was instrumental in changing the attitude of the sport towards safety, but it was 30 years or so after he retired before it reached the standard of safety that only allowed a driver to be killed very occasionally... Ayrton Senna for instance
