Discovery of canals on Mars
Percival Lowell was the first person to suggest "life"(intelligent beings) on Mars.
This came about because of the discovery of canals on Mars by Giovanni Schiaparelli in the 1890, that Lowell believed had been made by someone, not nature.
In 1894 Lowell built an observatory in Flag Staff,Arizona to study Mars.
Flagstaff has a high altitude,thin atmosphere and remote location so would give him a good view of the planet Mars.
He used a Clark telescope to view the full size images of Mars.
Then after that he went on to discover the ninth planet, Pluto in 1905.
