“I think the driving thing was curiosity about the universe. That fascinated me. I didn't think anything about being famous or anything like that, I was just interested in the concepts involved.”

Pluto was discovered #OTD in 1930 by Clyde W. Tombaugh, making it the first known object in the Kuiper belt. It was immediately hailed as the ninth planet. However, its planetary status was questioned when it was found to be much smaller than expected. via @wikipedia

The astronomer Clyde Tombaugh, discoverer of Pluto here shown with his homemade 9-inch telescope.

Clyde Tombaugh is shown here with his homemade 9-inch Newtonian reflector telescope. The image captures the young Tombaugh in shirt, tie, and glasses, standing beside the telescope he built himself from farm machinery parts and a mail-order lens while growing up in rural Kansas.
