About:

Godric Gryffindor valued courage, determination, chivalry, and strength of heart, and was described as one of the four most brilliant witches and wizards of his time. He was also the most tolerant and accepting of Muggle-borns out of the Founders, a point which brought about the end of his friendship with Salazar Slytherin. He was very forward thinking due to his creating the Sorting Hat to preserve the selection of the students after his time. This showcases his cleverness and creativity.
The name Godric is an Anglo-Saxon name in form, and can have several meanings, including, "he who rules with God" or "he who rules well". His surname is a reference to the half-lion magical beast, the Griffin, a fierce, legendary beast with the body of a lion, and the head and wings of an eagle. The Hogwarts house named after him uses a lion as its symbol. Furthermore, the last part of his surname, "dor", is similar to both the French d'or, "made from gold", "golden", which is one of the colours of his Hogwarts House, or the suffix dore, which means "gift of," in which case the meaning of "Gryffindor" would be "gift of the Gryffin." Gryffindor is also a pun on the golden griffin, which is a lion that only has eagle wings, so it has the head and front paws of a lion, and has golden fur and feathers. Even the French for Griffindor, Griffondor is a French homophone for the actual beast, Griffon d'Or.
Godric Gryffindor was named the July 2007 "Wizard of the Month" on Rowling's website. "One of the four famous founders of Hogwarts School of Witchcraft and Wizardry, Godric Gryffindor was the most accomplished dueller of his time, an enlightened fighter against Muggle-discrimination and the first owner of the celebrated Sorting Hat." J.K. Rowling once jokingly stated that if Godric Gryffindor was still alive: he would be the giant squid that lives in Hogwarts lake, that would make him the biggest Animagus (and, quite possibly, the oldest) in the Wizarding world. At the eleventh hour of each night the squid would change back into Gryffindor, who would wander the school grounds before returning to his squid form. It should be noted that Rowling was sarcastically trying to make a point, so obviously this statement is not considered canon. Godric Gryffindor is the only founder who is not mentioned to have any descendants, although for a time it was speculated that Harry Potter himself was a descendant of Gryffindor either through James Potter possibly because James hailed from Godric's hometown, or possibly through a line of Squibs to James' wife Lily Evans.
