Harry Potter

Godric Gryffindor is the founder of Gryffindor house. A fair man, he believed that any child who displayed magical abilities before their 11th birthday should be able to attend Hogwarts. Godric valued courage and bravery, believing these were the two most virtuous abilities a person can possess. Corresponds to the element of fire.

Helga Hufflepuff is the founder of Hufflepuff house; she was a kind and warm woman. The values a person must possess to be sorted into Hufflepuff house are those of loyalty, patience, and hard working above all else. It is also known that she brought the house-elves to Hogwarts. Corresponds to the element of earth.

Rowena Ravenclaw is the founder of Ravenclaw house, she was a sharp and intelligent woman. Intellect is a highly valued asset to the students of Ravenclaw house. Due to this, it is likely that Rowena wanted to make Hogwarts the very finest Wizarding school on earth, teaching those children with the highest intelligence. Rowena also had a daughter, Helena, who later became the Grey Lady of Hogwarts as a ghost. Helena stole her mother's diadem, and it became lost. It is well known that no one alive had seen it, however, in the Battle of Hogwarts, Harry Potter finds the diadem and destroys the horcrux within it. Corresponds to the element of air.

Salazar Slytherin is the founder of Slytherin house. Sly and cunning, he was not unlike many of the students he brought into his house. He believed strongly that only wizards of pure blood (i.e., those with a mother and father from wizarding families) should be allowed to attend Hogwarts. Slytherin caused great dispute over this with the other founders, and it eventually caused a permanent rift with Gryffindor, which led to Slytherin's departure from the school. Before he left, however, he created the Chamber of Secrets, complete with a huge statue of himself and a horrible monster. Corresponds to the element of water.
