CLYDE TOMBAUGH
The discoverer of Pluto signs a stunning 10x8 color photo of NASA artwork: the 9th planet appearing from behind its moon, Charon.
Photograph signed: "Discoverer of the 9th planet, Pluto/Clyde W. Tombaugh/Feb. 18, 1930". Color, 10x8 overall, image 9¼x6½ (one surface). Photo of NASA artwork by Pat Rawlings, depicting Pluto appearing from behind its moon Charon. Much printed information on verso about Pluto and its moons, dated February 1994. Clyde W. Tombaugh (1906-1997) 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 is traveling toward Pluto. Fine condition.
