During the 1920s, Philippe lived the life of a wealthy playboy, often found in the company of a beautiful woman, usually an actress, at one of the popular night spots in Paris. Philippe's older brother had made friends with
Robert Benoist when they served together in the ''
Armée de l'Air'' during
World War I and through this connection, for a short time Philippe took up
Grand Prix motor racing. From his father, he inherited the love of fast cars, but wishing to maintain a low profile Philippe used the pseudonym "Georges Philippe" in order to race anonymously. Rothschild raced his own
Bugatti T35C with moderate success, including coming fourth in the
1929 Monaco Grand Prix. He also made a brief appearance for the elite
Bugatti works team, but at the end of 1929 he abruptly withdrew from motorsport, to concentrate on the family wine-growing business. Rothschild made his first competition appearance in the
Paris–Nice auto race of 1928, competing in a borrowed
Hispano-Suiza. After purchasing a supercharged
Bugatti, the ex Targa Florio factory type 37A (37317)
T37, he adopted the pseudonym to protect his family. 'Georges Philippe' made his first appearance at the 1928 Bugatti Grand Prix at
Le Mans, a race solely for private Bugatti owners where he became second immediately after the winner André Dubonnet. For 1929, Rothschild decided to upgrade to a full Grand Prix-specification
Type 35C. In fact, he was so enamoured with the vehicles, he ordered three. Using one of the new cars,
Georges Philippe was entered into the Grand Prix d'Antibes. In a field that included
René Dreyfus and
Philippe Étancelin, both race winners many times over, Rothschild led the race until he crashed out on the 36th lap. A mere two weeks later, with the car rebuilt, Georges Philippe finished a highly creditable fourth at the inaugural
Grand Prix Automobile de Monaco, behind winner
William Grover-Williams. Continued improvement was finally rewarded when Georges Philippe won the
Burgundy Grand Prix three weeks later, finishing ahead of
Guy Bouriat in a second Rothschild T35C. However, he was unfortunate to retire from the following race while running sixth. The third of Rothschild's T35Cs was regularly campaigned by a rather curious acquaintance for a future Baron. A model and exotic dancer at the
Casino de Paris, Helene Delangle regularly took to the track under her professional pseudonym
Hellé Nice. Nevertheless, Georges Philippe had attracted sufficient attention to be offered a factory drive alongside Monegasque star
Louis Chiron. In his two races for the crack squad, Rothschild ran at the front of the field, before dropping back later in the race due to vehicle troubles. At the
1929 German Grand Prix, around the notorious
Nürburgring Nordschleife, Georges Philippe was comfortably ahead of Chiron before contact with a wall caused damage to his Bugatti's axle, slowing the car and allowing Chiron to pass and take the victory. Unfortunately, increasing fame was wearing Georges Philippe's anonymity rather thin. His final appearance was in the
1930 24 Hours of Le Mans where, driving an American
Stutz, he failed to finish. After this Rothschild quietly laid 'Georges Philippe' to rest, and returned to running Château Mouton Rothschild. In 1935, Rothschild and his friend, Jean Rheims, who were sponsoring a bobsled team, refused to participate in the 1936 Winter Olympics at Garmisch-Partenkirchen, Germany, protesting what they called the "persecution of Germans of Jewish religion." == Wine grower ==
