an 1881 novel written by mary shelley. arguably one of the earliest known works of science fiction and the origin point for one of fiction's greatest monsters, nobody has read it, because there's a more popular movie.
the plot concerns an obsessive doctor who believes he can synthesize his own life form, but upon doing so, he fails to raise it properly, leading to a very bad wedding, an expedition to the north pole, and many ponderous philosophical arguments.
differences from the source material: in the book, the monster was motivated by revenge outright, and was pretty chatty. since the 1931 movie, people have thought of frankenstein's monster as a voiceless, child-brained hulk who doesn't fully realize the consequences of his own actions.
to be absolutely clear, the monster is not named frankenstein. the monster is never given a name. but we can call him dave, if you like. in any case he is widely acknowledged as one of the all-time groovy ghoulies, like dracula and the wolf man
