Percival Lawrence Lowell (March 13, 1855 -- November 12, 1916) was an American businessman, author, mathematician, and astronomer who fueled speculation that there were canals on Mars. He founded the Lowell Observatory in Flagstaff, Arizona, and formed the beginning of the effort that led to the discovery of Pluto fourteen years after his death. The choice of the name Pluto and its symbol were partly influenced by his initials PL. Percival Lowell was a member of the wealthy Boston, Massachusetts, Lowell family. He was born in Cambridge on March 13, 1855, the brother of Abbott Lawrence Lowell and Amy Lowell. Percival graduated from the Noble and Greenough School in 1872 and Harvard University in 1876 with distinction in mathematics. At his college graduation, he gave a speech, considered very advanced for its time, on the nebular hypothesis. He was later awarded honorary degrees from Amherst College and Clark University. After graduation he ran a cotton mill for six years. In the 1880s, Lowell traveled extensively in the Far East. In August 1883, he served as a foreign secretary and counsellor for a special Korean diplomatic mission to the United States. He lived there for about two months. He also spent significant periods of time in Japan, writing books on Japanese religion, psychology, and behavior. His texts are filled with observations and academic discussions of various aspects of Japanese life, including language, religious practices, economics, travel in Japan, and the development of personality. Books by Percival Lowell on the Orient include Chosön: The Land of the Morning Calm (1886, Boston), Noto: An Unexplored Corner of Japan (1891) and Occult Japan, or the Way of the Gods (1894), the latter from his third and final trip to the region. The most popular of Lowell's books on the Orient, The Soul of the Far East (1888), contains an early synthesis of some of his ideas, that in essence, postulated that human progress is a function of the qualities of individuality and imagination.[citation needed] His time in Korea inspired Chosön: The Land of the Morning Calm. He was elected a Fellow of the American Academy of Arts and Sciences in 1892. He moved back to the United States in 1893.[2] Beginning in the winter of 1893-94, using his wealth and influence, Lowell dedicated himself to the study of astronomy, founding the observatory which bears his name. For the last 23 years of his life astronomy, Lowell Observatory, and his and others' work at his observatory were the focal points of his life. World War I very much saddened Lowell, a dedicated pacifist. This, along with some setbacks in his astronomical work (described below), undermined his health and contributed to his death from a stroke on November 12, 1916, aged 61. Lowell is buried on Mars Hill near his observatory. Lowell was an agnostic. Another of his books is The Eve of the French Revolution (1892). Astronomy career Lowell became determined to study Mars and astronomy as a full-time career after reading Camille Flammarion's La planète Mars. He was particularly interested in the canals of Mars, as drawn by Italian astronomer Giovanni Schiaparelli, who was director of the Milan Observatory. In 1894 Lowell chose Flagstaff, Arizona Territory, as the home of his new observatory. At an altitude of over 2,100 meters (6,900 feet), with few cloudy nights, and far from city lights, Flagstaff was an excellent site for astronomical observations. This marked the first time an observatory had been deliberately located in a remote, elevated place for optimal seeing. For the next fifteen years he studied Mars extensively, and made intricate drawings of the surface markings as he perceived them. Lowell published his views in three books: Mars (1895), Mars and Its Canals (1906), and Mars As the Abode of Life (1908). With these writings, Lowell more than anyone else popularized the long-held belief that these markings showed that Mars sustained intelligent life forms. His works include a detailed description of what he termed the 'non-natural features' of the planet's surface, including especially a full account of the 'canals,' single and double; the 'oases,' as he termed the dark spots at their intersections; and the varying visibility of both, depending partly on the Martian seasons. He theorized that an advanced but desperate culture had built the canals to tap Mars' polar ice caps, the last source of water on an inexorably drying planet.
