Robert O'Brien was an American driver who made a single Formula 1 start in 1952, driving for Simca in the Belgian Grand Prix at Spa. He finished twenty-third in that race, which remains his sole appearance in the World Championship.[1]
O'Brien's racing record is minimal; the one classified finish he achieved places him at an amateur level of competition. In that single outing, he finished ahead of Tony Gaze, a driver of considerably stronger standing, though this represents an isolated result rather than a pattern of competitive performance. Simca, the team he drove for, fielded a grid of eleven drivers across its history but accumulated no race wins and was anchored by Prince Bira as its strongest competitor.[2]
His active racing career spanned only 1952, after which he retired from the sport.
