Clyde Tombaugh didn't set out to discover Pluto when he sent his sketches of the night sky to Lowell Observatory in Flagstaff, Arizona in 1929. More than anything, he just wanted to get off the farm in Kansas where he spent his days working the earth.
At just 23 years old, Tombaugh sent his drawings, unsolicited, to several institutions and observatories around the United States, hoping someone — anyone — would give him some feedback on what he'd produced.
