Clyde William Tombaugh was born in Streator in 1906. As a young boy he was very interested in the universe and built his own telescope. He moved to Kansas to study astronomy at the state university. He became an assistant at Lowell Observatory in Flagstaff, Arizona at the age of 23. A year later in 1930, while working from reckonings made by Percival Lowell in 1914, Tombaugh discovered the most distant planet in our solar system, which he named Pluto.
