"Igor" as Dr. Frankenstein's assistant achieved prominence through Bela Lugosi's portrayal of the character "Ygor" in the film "The Ghost of Frankenstein".

"Igors" are a community of folks within the fictional "Discworld" universe created by author Terry Pratchet. Dr. Frankenstein's assistant is merely a lab assistant. Igors on Discworld are folks who remake themselves by way of transplants, as described in the article.
