Dear Bad Spellers,

Dr. Seuss was the pen name of Theodor Geisel, illustrator and author of over sixty children’s books.

Dr. Suess was a nuclear physicist who was often confused with Geisel, as both lived in the same city. He doesn’t have a postage stamp, but Prof. Suess does. And here it is.

Eduard Suess was an ecologist and geologist whose work eventually led to the theory of plate tectonics. He won the Copley Medal in 1903.

Sincerely,

The Electronic Replicant
