As many of you know by now, I’m in the middle of editing The Pure World Comes, a Gothic horror novel I wrote earlier this year. The novel follows a maid living in Victorian England who goes to work at the estate of a mad scientist (yes, that’s my elevator pitch for the story). Since a mad scientist features prominently in the story, I thought I’d take a moment to discuss the trope, as it’s extremely common in fiction, especially sci-fi and horror.
With that being said, I decided to do some research before working on The Pure World Comes. I couldn’t find many articles on the trope (and those I did were pitifully short), so I asked one of my Facebook writing groups for help. I got way more responses than I’d expected. Some of them gave me some funny responses like including wild, white hair and a funny accent, or differentiating mad scientists, who do mad experiments, to mad engineers, who build mad things. Some were not helpful at all, like imagining them as autistic overachievers (excuse me? I’m on the spectrum and an overachiever! I take offense at that).
However, there was some good information given to go with the few articles I could find. To start with, the mad scientist trope is over two-hundred years old, with the prototypical mad scientist being Victor Frankenstein of the novel Frankenstein.* However, the stereotypical look of the mad scientist–wild hair, crazy eyes, and “quasi-fascist laboratory garb1“–as well as the outlook for the lab, was influenced by the character Rotwang and his lab in the German silent film Metropolis. Rotwang also had numerous traits we associate with mad scientists (more on that later). After the horrors of WWII, such as German experiments and the atom bomb, and the outbreak of the Cold War, mad scientists began to reflect the horrors and fears of that age, often working on projects that could destroy all or almost all of mankind.
Given the state of the world now, I’m expecting an influx of mad scientists interested in virology and/or social engineering.
Alongside their history, I found out mad scientists have some common subtypes:

- Mythical scientists. These are the mad scientists who seem to be working with godlike powers, either through unexplained, futuristic science bordering on magic or actually studying/utilizing magic items. Science-colored wizardry, as one FB commenter put it.
- Unethical scientists. These are the scientists who are actual scientists but have dropped their ethics/morals. These types are usually based on the Nazi scientists, the Tuskegee doctors who studied on unknowing black men, and so many more (sadly), though Frankenstein technically falls into this category.
- Cutting edge obsessive scientists. These types aren’t always so bad. They are good at their work and love it deeply, but tend to get obsessive to the point it can cause trouble for them or other characters. Often, after causing a lot of trouble, they can get a redemption arc. A good example is Entrapta from the She-Ra reboot.
- Scientists with mental illness. These are self-explanatory, and are becoming more and more common in media these days. This can be a bit of a double-edged sword, as it can be great representation for the disabled, but it can also give a bad name to the disabled by linking their evil behavior to their mental illness.
Obviously, these types can cross over with each other. And there’s probably more than what I’m listing here.
Whatever their type, type combination, or era of creation, all the types have some commonality. For one thing, they generally deeply believe in their goals or research. They also tend to think of themselves as a protagonist in their own personal story. Even the ones who acknowledge they’re evil still believe they’re a main character on the world stage. Pride, greed, or the belief that they know better is generally what drives them, and is often what leads to their downfall.
As for how to write mad scientists, it’s less having to do with the trope and with the character itself. Because of what the mad scientist can do, they’re often used to fulfill a number of needs in stories, but unless you’re making them a satire of the trope or just including them for comical effect, you need to really think about their character. What motivates them? What are their odd ticks or quirks? Think of them like you would any other character and apply the same amount of love and development. Hopefully then you can create a great mad scientist.

You can also try going against clichés. Most mad scientists are older white males with nefarious intentions, so going against one or more of these traits and then making the character your own might be a good idea. Looking at you again, Entrapta from She-Ra! You wonderful, robot-obsessed, magic-haired princess, you!
Mad scientists are common characters in fiction and for good reason. And while there’s no sign they’re going away any time soon, there’s plenty of room to innovate and make them your own. Especially if you do your science homework before you start writing.
That’s all for now, my Followers of Fear. This will probably be the last post I make for 2020. If that’s true, I’ll catch you all next year. In the meantime, I’ll be bingeing TV, sleeping and editing The Pure World Comes (I’m currently in the chapter where I reveal who Jack the Ripper is).
Until next time, stay safe (and don’t travel), Happy New Year, and pleasant nightmares!
*Fun fact, Victor Frankenstein never actually finished college, so he’s not a doctor, though people think he is. But since the discipline of science hadn’t been formalized and all the other stuff by the early 19th century, we can still call him a mad scientist.
