Percival Lowell

Died 12 Nov 1916 at age 61 (born 13 Mar 1855).American astronomer who predicted the existence of the planet Pluto and initiated the search that ended in its discovery. Lowell was also passionately committed to finding proof of intelligent life on Mars. In 1894, he founded the Lowell Observatory, atop Mars Hill, at Flagstaff as Arizona's first astronomical observatory. Studying Mars, Lowell drew in intricate detail, the network of several hundred fine, straight lines and their intersection in a number of "oases." Lowell concluded that the bright areas were deserts and the dark ones were patches of vegetation. He believed further, that water from the melting polar cap flowed down the canals toward the equatorial region to revive the vegetation.
