Professor Phineas Potter is a fictional character who appeared in various Superman and Superboy stories published by DC Comics. He was the uncle of Lana Lang (her mother's brother), and first appeared in Superman's Pal, Jimmy Olsen #22 in August 1957.
An eccentric scientist, Professor Potter often appeared in various stories as an inventor of odd or fantastical devices, such as a device that (in Potter's first appearance) briefly evolved Jimmy Olsen into a superintelligent being from one million A.D.. He would also contribute his scientific prowess on occasion to assist the cast of Superboy/Superman characters.
Potter made sporadic appearances over the years; however, after John Byrne's revamp of Superman's mythos in 1986, Potter fell by the wayside as a character, largely being replaced in his role by Professor Hamilton . However, a modern version of Potter appeared in the most 1990s Superboy title, as an employee of a branch of S.T.A.R. Labs in Hawaii.
