Google Stump

Google Stump was a shy, timid and stuttering wizard. He had a portrait of himself hung on Hogwarts Castle. By 1995, the portrait was in the Viaduct Entrance. Guarding a secret passage from there to the First Floor Corridor, no one had told him the password. When confronted by Harry Potter, who asked if he was really doing his job if no one used his shortcut, the portrait told the student the password. The password, Volo futurus unus, meaning in Latin "I want to be alone", brings out the shyness of the wizard. Later in the school year, he directed Harry Potter, Ron Weasley and Hermione Granger to the portrait of Giffard Abbott to obtain the password to access the shortcut behind Percival Pratt's portrait.

Behind the scenes
He may have been related to former Minister for Magic Grogan Stump.
