means clyde tombaugh, the astronomer who discovered pluto in 1930 using painstaking photographic comparison, no supercomputers, just eyes and patience.

from born 1906 on a nebraska farm, tombaugh ground his own telescope mirrors from spare parts after hail wrecked his crops, sent sketches of jupiter and mars to lowell observatory, and got hired despite having no college degree, then spent a year blinking through photographic plates until pluto twitched into view.
