Corvinus Gaunt

Corvinus Gaunt was a wizard of the XVIII Century, member of the Gaunt house. He had the ability of talking to snakes. He opened the Chamber of Secrets while studying at Hogwarts.

When first created, the Chamber was accessed through a concealed trapdoor and a series of magical tunnels. However, when Hogwarts' plumbing becamemore elaborate in the eighteenth century, the entrance of the Chamber was threatened, being located on the site of a proposed bathroom.

The presence of Corvinus, who was a student in the school at that time, explains how the trapdoor was secretly protected, so that those who knew how could still access the entrance to the Chamber even after newfangled plumbing had been placed in top of it.
