On a marché sur la Lune
Mr. Baxter is the Director General of the Sprodj Atomic Research Centre, appearing in "Destination Moon" and "Explorers on the Moon". He is humble, refusing to go to the Moon in Captain Haddock's place when it is offered it to him, and he works well with Professor Calculus, whom he supports completely. He misses most of the excitement of the Moon journey, having to stay and man the Centre, but acquires some of it when the returning Moon rocket nearly lands on his car.
