Richard "Dick" Wood (pen name Dick Hamilton) is an American scriptwriter for comic books.
Wood's most distinctive stylistic quirk lies in his interjections. Y-yipes and Thunderation, among other things, are interjections Wood uses elsewhere. Some singular expressions from the two stories in Mandrake the Magician #2 indicate Wood as the script-writer, as: Suffering Hannah and Great suffering Caesar. 
Wood might be the writer of both stories in Mandrake the Magician #3. As in succeeding stories, Lothar refers to himself as Lothar, not I, and his dialogue gets a bit dumber.
