There's no Igor in the book either!
Igor has become a 'type' rather than a character. The first Igor was actually called Fritz and comes from the first (I think it was the first) Bela Legosi Frankenstein movie in the 30's. I believe the name was changed to Igor in later movies (though its basically the same character) and then it became short-hand for "mad scientists assistant" and Igors went on to feature in various non-frankenstein media.
