However, Aminadab, Aylmer's assistant, was an original creation. I came to this conclusion because, after much research, I found out that in Shelley's novel, Victor Frankenstein doesn't actually have an assistant. The well-known helpers that we as an American public have become familiar with were only popularized in the movies. Which is a shame, as that was the most important similarity I noticed in the reading.
In 'The Birthmark', Aminadab, Aylmer's "under-worker" seems to represent man's physical nature. A weird man endowed with "vast strength" and "indescribable earthiness," he understands how Aylmer's attacks on Georgiana's body spell doom. He remarks, "If she were my wife, I'd never part with that birth-mark". Aminadab understands early on that the attempted removal of the mark will probably kill Georgiana, yet in the end when she does die, he laughs.
In the popular movie versions of 'Frankenstein' we have been exposed to many different assistants, such as Fritz and Igor. All of them possessed some of the strength and earthiness Hawthorne describes in 'The Birthmark'. Some were funny, some were scary, but I have had to expound on my original theory. Perhaps the "under-worker" most people are familiar with today came from a compilation of the two stories. For sure, the basic plot of 'Frankenstein' has evolved today to be synonymous with the mad scientist and his strange assistant. The story just isn't the same without that character. My personal favorite is Igor from 'Young Frankenstein' (See clip
