Percival Lowell, Mars, and the Canals

The Italian astronomer Giovanni Schiaparelli in 1877 was the first to report the presence on Mars of "canali" , an Italian word meaning naturally occurring channels, like river channels.

Percival Lowell (1855-1916) was one of the best known observers of the planet Mars. He established an observatory (now Lowell Observatory ) in Flagstaff, Arizona for the express purpose of observing the Martian "canali", which Lowell mistranslated as "canals". He concluded that these canals were built by intelligent beings to supposedly supply water from the melting polar caps to a desert world.

Lowell's misunderstanding and overactive imagination led to the notion that Mars was inhabited by intelligent beings who were capable of planet wide engineering projects, and is the source of many science fiction stories about the red planet.
