Percival Lowell ( March 13, 1855November 13, 1916) was a wealthy amateur astronomer who was convinced that there were canals on Mars, and was the founder of Lowell Observatory in Flagstaff, Arizona.

Percival Lowell came from the distinguished Boston Lowell family. In addition to his own accomplishments his younger brother Abbott was president of Harvard University, and his sister Amy Lowell was a well-known Imagist poet and critic.

February 14 Alexander Graham Bell a with distinction in mathematics, and traveled extensively through the Far East before deciding to study Mars and astronomy as a full-time career. He was particularly interested in the supposed canals of Mars, as drawn by Giovanni SchiaparelliGiovanni Virginio Schiaparelli ( March 14, 1835 July 4, 1910) was an Italian astronomer. He studied at the University of Turin and Berlin Observatory and worked for over forty years at Brera Observatory. He observed objects in the solar system, and after, who was director of the Milan Observatory and an esteemed Italian astronomer.

At an altitude of over 7000 feet, and with few cloudy nights, it was an excellent site for astronomical observations. For the next fifteen years he studied Mars extensively, and drew intricate drawing 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). He thereby instigated the long-held belief that Mars had once sustained intelligent life forms.

Lowell's greatest contribution to planetary studies came during the last 8 years of his life, which he devoted to the search for Planet XSol System planets Planet X (or Transpluto) is a hypothetical planet beyond Pluto. Its existence was argued for on the basis of apparent discrepancies in the orbit of Neptune. A common name for this hypothetical planet is Persephone. Reasons for Planet X', which was the designation for a planet beyond Neptune. The search continued for a number of years after his death at Flagstaff in 1916; the new planet, named PlutoPluto is the ninth planet from the Sun in our solar system. Because Pluto is also the smallest planet in our solar system and has a highly eccentric orbit (which takes it inside the orbit of Neptune) there has been some debate regarding whether Pluto shou, was discovered by Clyde TombaughClyde William Tombaugh ( February 4, 1906 January 17, 1997) was an American astronomer who discovered the planet Pluto in 1930. He made the discovery at Lowell Observatory in Flagstaff, Arizona, during a systematic search for a trans- Neptunian planet (al in 1930. The symbol for the planet is a stylized "PL" (♇), chosen in part to honor Lowell.

It is interesting to note, that predictions of a planet beyond Neptune were based on discrepancies between the predicted and observed positions of Neptune and Uranus, and the erroneous assumption that such discrepancies were caused by the gravitational influence of an unknown planet. In fact, the discrepancies were due to erroneous values for the masses of Neptune and Uranus; with modern precise values, the discrepancies disappear, and in any case it is now known that the mass of Pluto is far too small to exert any appreciable gravitational influence on other planets.
