A member of that family is found a lot on stamps: the famous writer and aviator Antoine de Saint-Exupéry (1900 — 1944).
He is best remembered for his novella The Little Prince ("Le Petit Prince").
I love his books about aviation adventures, including Night Flight ("Vol de Nuit") and Wind, Sand and Stars.
He was a successful commercial pilot before World War II, joining the Armée de l'Air (French Air Force) on the outbreak of war, flying reconnaissance missions until the armistice with Germany. Following a spell of writing in the United States, he joined the Free French Forces.
