Many are familiar with the hunchbacked assistant of Doctor Victor Frankenstein known as Igor, however most people fail to realize that he was not part of the original novel. Indeed, Igor was not even present in the widely successful 1931 film Frankenstein. The original hunchback assistant of the infamous doctor was named Fritz, who unfortunately met his demise at the hands of the Monster after tormenting it with a flaming torch. Sequels of the film, notably Son of Frankenstein, featured a character named Igor, though he was neither hunchbacked nor a lab assistant but rather a blacksmith.
The confusion behind Igor’s role as a hunchbacked assistant may come from the 1953 adaptation of the classic horror film House of Wax. In this movie, the museum curator’s assistant was named Igor, though he was not hunchbacked, but rather deaf and mute.
The similarities between Gothic horror films at the time all took inspiration from the classic Frankenstein movie, and over decades morphed an idea of the original source material which was separate from the novel.
