		Clyde William Tombaugh (February 4, 1906 - January 17, 1997) was an American astronomer who discovered the planet Pluto in 1930.
		Tombaugh's discovery involved painstaking use of a blink comparator - a device which allows someone to compare two similar photographs by placing them in the viewer's field of vision, and then letting the user switch back and forth - blink - between the two.
		Tombaugh was employed at the Lowell Observatory from 1929 to 1945.
