That seminal event in astronomy was largely to the credit of the astronomer Percival Lowell.

It named the object Pluto, in part because the first two letters in the name were Percival Lowell's initials.

As a child, Gernsback discovered American astronomer Percival Lowell's writings about canals on Mars, inspiring his love of amazing stories.

Pluto was labeled a planet when it was first discovered in the Percival Lowell Observatory by Clyde Tombaugh in 1930.

Convinced that the canals were real, US astronomer Percival Lowell mapped hundreds of them between 1894 and 1895.

Although Pluto became Lowell Observatory's most famous discovery, Percival Lowell had founded his observatory in 1894 to find proof of intelligent life on Mars.

Tombaugh's object became known as Pluto, for the Roman god of the underworld, with a nod, in the first two letters, to Percival Lowell.

The date is the birthday of Percival Lowell, the astronomer that posited the existence of a "Planet X" beyond the orbit of Neptune.

Lowell Observatory revealed Tombaugh's find to the world on 18 March 1930, on what would have been Percival Lowell's 75th birthday.

Mr. Percival Lowell has truthfully observed that the Japanese speak backwards, read backwards, write backwards,-andthat this is "only the abc of their contrariety."

In his brilliant but fallacious volume, entitled "The Soul of the Far East," Mr. Percival Lowell states that the Japanese do not "fall in love."

Percival Lowell also, as we have seen, makes light of Japanese religion.

Percival Lowell did not live to see a trans-Neptunian world found (he died in 1916).
