CLYDE WILLIAM TOMBAUGH
Pamphlet with three reprinted papers on astronomy, originally published in 1937, by three astronomers, including Clyde William Tombaugh, signed "With the compliments of the authors". This pamphlet shows that Tombaugh continued to contribute to astronomy after his discovery of Pluto.
Pamphlet signed "With the compliments of the authors./- CWT." in blue ink. B/w, 16 pages, 5¾x9, bound in grey cardstock covers with two staples. This pamphlet includes three papers by three different astronomers, including Tombaugh, reprinted from the October 1937 edition of the Publications of the Astronomical Society of the Pacific. Tombaugh's article is titled: "The Great Perseus-Andromeda Stratum/Extra-Galactic Nebulae and Certain/Clusters of Nebulae Therein as/Observed at the Lowell/Observatory". Tombaugh is best known for discovering Pluto, which was until recently considered the ninth planet in our solar system, in 1930. But Tombaugh continued to watch the skies and contribute to astronomy after the discovery, as can be seen by this paper, published over seven years after his landmark discovery. Tombaugh (1906-1997, born in Streator, Illinois) was hired in 1929 as an assistant by the Lowell Observatory in New Mexico to continue the search for a planet beyond Neptune, which had been initiated by Percival Lowell. Tombaugh used a blink microscope to compare photographs of a small part of the night sky and detect the planet. After ten months of painstaking comparisons, on February 18, 1930 he found Pluto in the constellation Gemini. Some of his ashes are carried on the New Horizons spacecraft, which was launched on Jan. 19, 2006 and is scheduled to fly by Pluto and its moon Charon in 2015. Lightly toned and creased. Lightly rounded left corners. Otherwise in fine condition.
