Clyde Tombaugh: At that time, the Lowell Observatory was the only planetary observatory in the country, and I was particularly interested in planets at that time, so I thought I would just like to see what they think of them. Of course, the planets are never the same twice; they’re always different. And so they could see from my drawings — they could compare the markings I had drawn with their current photographs, and they knew that I was drawing what I was really seeing, and it wasn’t copied from somewhere. So they realized that I was careful, I saw well, and so on, and so they thought I would be a good candidate to run this new photographic telescope they were installing.
