Fictional character biography
When J. Jonah Jameson first hired Peter Parker, he was amazed at how he managed to obtain pictures of Spider-Man. He hired private investigator Mac Gargan to look into this. When Jameson saw an article about inducing animal mutations into humans, he visited the scientist that established this experiment: Dr. Farley Stillwell. Jameson first thought Stillwell was a crackpot, but later saw him as an opportunity to take down Spider-Man. When he first went to see Dr. Stillwell in his lab, Jameson had him experiment on Gargan. Stillwell gave Gargan a high-tech scorpion-suit, and the Scorpion was born. Shortly after the experiment, Stillwell ran some tests and found that his experiment wasn't a true success. He discovered that Scorpion would lose his sanity as he got stronger. Creating an antidote, Stillwell headed to where Spider-Man was fighting the Scorpion. Upon learning the side effects of the formula from Stillwell, Scorpion didn't want to lose his powers and climbed up a building. Stillwell went up after him and lost his grip. As he fell, Dr. Stillwell threw the serum at Gargan in a vain attempt to cure him. He missed and fell to his death.

Legacy
It was later revealed that he had a brother named Harlan Stillwell who used the experiment to create the Human Fly after being held at gunpoint by Richard Deacon. After Richard became the Human Fly, he shot Harlan.

The Stillwell brothers' technology would also later be used to give superpowers to the Answer, and the fourth Vulture.
