On this day in 1944, Greek-French astronomer Eugène Michel Antoniadi passed away in Paris, France.
Mr. Antoniadi was one of the astronomers that battled the idea of a civilization creating canals on the surface of Mars, putting him at odds with American astronomer Percival Lowell. While he was initially open to the idea, he later believed the canals to be an optical illusion.
