Vanderbilt Cup Races

Gabriel began his career in 1899 at the tour de France for automobile 1899, where he was able to achieve a class victory. He achieved his greatest success with racing Mors cars. A victory at the Ardennes race 1902 was prevented only due to a breakdown on the last lap, he had to be content with second place. His greatest triumph was winning the race 1903 Paris-Madrid Race. The race was due to several fatalities (including Marcel Renault) cancelled in Marseilles (he was more than 15 minutes faster than the competition on the 552 km) is still as a gem of Gabriel's gauging performance in this race.

After this success, the star of Gabriel's began to decline, probably also because he had no competitive material available. He drove a De Dietrich at the 1904 Vanderbilt Cup Race and a Lorraine-Dietrich the 1908 French Grand Prix. He also drove for Clément Bayard. After the first World War, he competed with Sonderklasse and Hill climb.

He later worked  in the Renault car factory in Paris. He died in 1943, when the factory was bombed by the Royal Air Force.
