Fernand Henri Chavannes
Sous Lieutenant Fernand Henri Chavannes was a World War I flying ace credited with seven aerial victories. Chavannes was the son of renowned sinologist and Chinese scholar Édouard Chavannes.
Chavannes and his friend Lionel de Marmier were chosen to share a new "cannon Spad", the SPAD XII, when it came out in mid-1917. The letters "M" and "C", representing their last names, were intertwined in paint on the side of its fuselage.
