The prototypical caracature mad scientist, I wondered about this years ago but didn’t get an answer then
Let’s backtrack a bit.
The prototypical caricature of Jesus we know. The first images of Jesus that have survived showed him to have a girlish beardless figure. Then someone adapted the bearded image of Thor and called it Jesus and that became the standard. More recently, the image form the Turin shroud has become the standard.
The prototypical caricature Santa Claus we know. With his wild white beard and hair, his rotund jolly face, and red coat. His red and white look came from Coca Cola ads of 1931.
The prototypical circus clown with red nose, white face, baggy clothes, permanent smile and wild hair. I only just found out about that, but it’s been known for some time. This parody was invented by Joseph Grimaldi. He first appeared on stage as a clown in 1781 at age three at Saddler’s Wells Theatre. His most famous clown first appeared in 1806 at covent Garden Theatre.
The prototypical Mad Scientist.
“The movie Metropolis (1927) brought the archetypical mad scientist to the screen in the form of Rotwang, the evil genius whose machines had originally given life to the dystopian city of the title. Rotwang’s laboratory influenced many subsequent movie sets with its electrical arcs, bubbling apparatus, and bizarrely complicated arrays of dials and controls. Portrayed by actor Rudolf Klein-Rogge, Rotwang himself is the prototypically conflicted mad scientist; though he is master of almost mystical scientific power, he remains a slave to his own desires for power and revenge. Rotwang’s appearance was also influential—the character’s shock of flyaway hair, wild-eyed demeanor, and his quasi-fascist laboratory garb have all been adopted as shorthand for the mad scientist “look.” Even his mechanical right hand has become a mark of twisted scientific power.”
Rotwang from Metropolis.

Rotwang doesn’t wear a white lab coat. We had to wait four years for that. In the Movie Frankenstein in 1931 the lead character does wear a white lab coat. But doesn’t have the typical mad scientist face.

They come together with the test tubes and chemical apparatus in addition to the white lab coat for the first time in Dr. Meirschultz, a scientist attempting to bring the dead back to life in the 1934 film Maniac.
