Pierre Raymond Sommer was a French racing driver. He raced both before and after WWII with some success, particularly in endurance racing. He won the 24 Hours of Le Mans endurance race in both 1932 and 1933, and although he did not reach the finishing line in any subsequent appearance at the Le Mans, he did lead each event until 1938. Sommer was also competitive at the highest level in Grand Prix motor racing, but did not win a race. He won the French Grand Prix in 1936, but the event that year was run as a sports car race.

Aix-les-Bains, Savoie, France had a race track, called Circuit du Lac, which hosted Formula 2, Formula Junior, and Motorcycle Grand Prix races between 1949 and 1960.
