I submit to you God, in the form of Jesus. According to the bible he invented man who then killed him.
Dr. Robert Atkins?
Wasn’t one of the Wright brothers killed while demonstrating their airplane ?
didn’t he die from a fall in the shower?
No, although Orville suffered nasty injuries in a crash.
And Orville’s passenger, Lt. Thomas Selfridge, was killed.
There have been way too many “self-taught aeronautical engineers” who didn’t survive the first test flights of their creations. And some serious, pioneering ones, too - Otto Lilienthal in one of his hang gliders is a notable example.

That’s the video I have. IIRC there’s a neurosurgeon who states that the nerves, muscles, etc. for blinking the eyes are all intact after decapitation and it takes 15 seconds or so for the oxygen supply to the brain to be used up.
There’s Seth Brundle whose invention turned him into a fly-man, that ultimately lead to his death. Never drink and teleport.
Does Thomas Andrews count? Shipbuilder of the Titanic. Was on the ship when it, well, I don’t want to spoil it for those who haven’t seen the movie yet…
He died when his own ship was overrun by alien “vessels” from the heavens. Using some sort of “Ice-Ray”, the aliens blew several gashes into the side the oceanliner, and it sunk into the depths of the Atlantic. Although, it’s witnessed, most left treading the water were actually abducted by these advanced beings. Could Thomas Andrews still be out there, somewhere?! We may never know.
George Jackson Churchward CBE, renowned chief mechanical engineer of the Great Western Railway (UK) from 1902 to 1922. The designer of many successful classes of steam locomotive, featuring much standardisation of components across classes, was struck and killed by a GWR locomotive. This was some years after his retirement and I’d be interested to learn if it was one of his own design.
It’s been a while since I read it, too, but doesn’t the monster also learn to read, and at the end is able to converse in the manner of an educated person?
So no one is reading the blog linked in the OP?
Or other posts in this thread?
Or neither?
Horace Lawson Hunley, designer of the confederate submarine.
William Bullock, inventor of the web rotary printing press, killed by his own press.
The monster is way more eloquent and articulate than any movie has ever shown and learns to read and write early in the book.
As for what happens in the end:
Dr Frankenstein chases the monster to the North Pole ice sheet, when he almost gets him he falls in the water and is rescued by an exploration ship. Goes back home (I think) gets sick and dies. The monster goes to visit, breaks the violins, throws a weeping monologue and in shame and remorse goes back to the North Pole where, presumably, it dies.
Sigh.
I think it’s time you to DESTROY THEM!!! 
Nobody seems to have mentioned Sir Francis Bacon who is said to have died of frostbite having ‘invented’ the preservation of food via freezing by stuffing a chicken full of snow. It’s not mentioned on Wikipedia - is it simply not true?
We’ll change that when we get home, We’ll change a lot of things.
As I recall, some accounts (although it’s apparently far from a sure matter of record) say that Johann Conrad Dippel died as the result of an alchemical experiment.
I thought I remembered reading, somewhere, that the inventor of Phosgene died from exposure to the gas, but I checked it awhile back, and it turns out it isn’t so. (Rather a pity, as it was a good story.)
