Edgar Allan Poe is the founder of horror literature. As a child, he used a terrifying method to remember his lessons more easily. For this purpose, he went to the cemetery, NOVA reported.
Edgar Allan Poe studied at a school with very poor students. Their parents could not afford to buy textbooks. Their math teacher made them go to cemeteries. There they had to make all sorts of calculations with the years of birth and death of the deceased.
Interestingly, throughout his life Poe was afraid of the dark.
