Percival Lowell

Percival Lawrence Lowell (March 13, 1855 – November 12, 1916) was an American businessman, author, mathematician, and astronomer who made significant contributions to planetary science during the late 19th and early 20th centuries. After a successful career in business and diplomacy, Lowell devoted himself to astronomy, establishing the Lowell Observatory in Flagstaff, Arizona, in 1894. He became famous for his detailed observations of Mars and his theory that the planet's surface contained a network of canals built by an advanced civilization. Though his canal theory was eventually disproven, Lowell's meticulous work advanced telescopic astronomy and his observatory made important discoveries, including the detection of Pluto in 1930, fourteen years after his death. His popular writings helped spark public fascination with astronomy and the possibility of extraterrestrial life. Lowell's legacy extends beyond his scientific contributions; he exemplified the era when wealthy patrons could advance scientific knowledge through dedicated observation and rigorous documentation.
