History is ofte thought of a team sport. In school, we study history so that we don't repeat it.

In society, research and breakthroughs made by a certain team will help unlock answers for the next group of people.

However, there are some historical inventions, advancements, or even failures that come down to the actions and decisions of just one person. These historical figures are still talked about today.

Curious to learn more, Redditor MisterDecember asked:

"What decision by a single person had the biggest impact on human history?"


Words On A Page

"My man, Johannes Gutenberg. This was also my answer as he ushered in the modern period of human history. His work developed the Renaissance, Reformation, Age of Enlightenment, and Scientific Revolution (as well as laying the material basis for the modern knowledge-based economy and the spread of learning to the masses)."

"He also never profitted from his invention and died in poverty."

"GUTENBERG, DARN TOOTENBERG. Pretty cool dude. More people need to know his story. They even made a musical!"

"Alexander Fleming was a sloppy medical researcher in the 1920s who returned from a 2 week vacation to find he had left out one of his culture plates and it had grown over with mold."

"Most lab technicians would never have allowed this to happen in the first place. If it did happen, they would have immediately scrapped the mess and thought nothing else of it. Fleming decided to take a close look out of curiosity ... and discovered that this mold made destroying bacteria its business. And business was good."

"He had discovered penicillin. And birthed essentially the entire field of successful, safe antibiotics, revolutionizing medicine the world over practically overnight."

Poor Military Decisions

"The decision of John F Kennedy to ignore the unanimous recommendation of his military advisors to launch air strikes on Cuba in October, 1962. Close second, the decision of Nikita Kruschev to offer a deal to Kennedy as a way out of the Cuban Missile Crisis."

The Dangers of Lead

"Thomas Midgley Jr. He put lead in gasoline which led to a measurable decrease in IQ and a probable increase in crime rate."

– Hungry_Treacle3376

"This guy KNEW about the dangers of lead and still used it. Lead-based items were already known to be toxic at this time, but despite that, he had said at a public health conference he said, "we do not feel justified in giving up what has come to the industry like a gift from heaven on the possibility that a hazard may be involved in it", which is absolutely evil."

Whether that difference is good or bad is another story!

People Divulge Which Instances Of The Mandela Effect Freaked Them Out The Most

The Mandela effect is when multiple people share the same, incorrect memory.

Its name stems from when paranormal researcher Fiona Broome falsely believed that the future president of South Africa, Nelson Mandela, died in prison in the 1980s.

A false memory she shared with a number of others.

Our memories have been known to deceive us, as we might frequently forget someone's name or one of our numerous online passwords.

But when we share a memory that turns out to be false with many others, convincing ourselves it wasn't the truth can be a very difficult ordeal indeed.

Most of the time, this isn't intentional, but just simply happens.

On rare occasions though, people might realize that their friends were not exactly who they thought they were, and didn't like who they revealed themselves to be.

For that matter, even locals might need a refresher course on what they can and can't do while at home.
