Eugene Michel Antoniadi was a Greek astronomer. He spent most of his life in France. So, on the internet we can find him as a French and Turkish astronomer. Antoniadi was also a very successful chess player.
He studied architecture and he drafted archaeological drawings of the church of Hagia Sophia in Constantinople.
Antoniadi became a reputed observer of planet Mars. His top observations were straight canals on planet Mars, which looked like dark lines. Antoniadi concluded that the canals were optical illusions, something that was confirmed by the spacecraft missions to the planet several years later.
Through countless hours of observations he made the first detailed map of the surface of the ‘red planet’. This project was completed by John E. Fokas and the main features of Mars (mountains, areas, craters) have got greek names.
Eugene Antoniadi observed the inside planets Venus and Mercury and tried to draw a map of Mercury. But his efforts were flawed and based on the assumption that Mercury turned always the same hemisphere towards the sun. He invented the scale for the quality of seeing widely used today by amateur astronomers.
Eugene Antoniadi played chess against great players of his time. In the 1907 tournament in Paris he won the first place.
The craters Antoniadis on Mars and
Antoniadi on the southern hemisphere of the Moon have taken their names from this famous astronomer!
