Clyde Tombaugh 1

Let's begin at the beginning. How did you first know what you wanted to do in your life?

Clyde Tombaugh: When I was in the fourth grade, I became intensely interested in geography and I learned it well. In fact, by the time I was in sixth grade I could bound every country in the world from memory. By then the thought occurred to me, "What would the geography be like on the other planets?" So that was my natural entrance into astronomy, you see. So I've been interested in that area particularly ever since.
