The French Open tennis tournament is named after aviator Roland-Garros. What did he do?

Roland Garros gained fame for making the flight from Fréjus in France to Bizerte in Tunisia. The following year, Garros joined the French army at the outbreak of World War I. Garros is sometimes erroneously called the world's first fighter ace. In fact, he shot down only four aircraft; the definition of "ace" is five or more victories.
