He attended Baltimore Polytechnic and John Hopkins University, graduating in 1929. He worked as a curator at the Maryland Academy of Science observatory and as a director at the Davis Planetarium, where he worked for twenty-five years. Watson introduced hundreds of thousands of children, their parents, and teachers through lectures and demonstrations.
