6 The "witches" of the salem trials were burned at the stake
There are no records of people being burned at the stake during the Salem Witch Trials. The Accused were either hanged or died while in prison.
More died in prison than were hanged.
7 Vikings wore horns on their helmets
If they actually did that in real life, it would be dangerous!
8 Napoleon Bonaparte was short
In fact, Napoleon was slightly taller than the average Frenchman of his time. The problem comes from the difference between French inches and English Inches. He was actually about 5 foot 7 inches tall.
This could be a result of there being so many tall men being use in the military, so that he appeared short in comparison.
Napoleon was actually around 5'6 / 5'7 which was actually pretty average for his time.

Professional laborers built the pyramids.

13 Iron Maidens were used as torture devices in the Middle Ages

Its just the people before Columbus era and the Flat Earth Society nowadays.

He did fail the entrance exam to the Swiss Federal Polytechnic School his first time but then again he was 2 years younger than his peers and scored exceptionally well in math and science.

Another invention taken from Tesla. Tesla sued him for that and won the battle and the rulling said he is the true inventor of the radio.
