Which actor did not play the character Dr. Art Schivel (Mr. Freeze) in the Batman TV series?

"Batman" is a 1960s American live action television series, based on the DC comic book character of the same name. It stars Adam West as Bruce Wayne (Batman) and Burt Ward as Dick Grayson (Robin), two crime-fighting heroes who defend Gotham City from a variety of archvillains. It is known for its camp style, upbeat theme music, and its intentionally humorous, simplistic morality (aimed at its largely teenage audience). This included championing the importance of using seat belts, doing homework, eating vegetables, and drinking milk.

Victor Buono played the part of Professor William McElroy (King Tut) an Egyptologist who developed a split personality after being struck on the head during a student protest. Each time he is hit on the head, he switches between the personalities of a university professor and a reincarnated version of the pharaoh Tutankhamun.

Dr. Art Schivel (Mr. Freeze) played by George Sanders (Season 1), Otto Preminger and Eli Wallach (Season 2). A mad scientist who, after exposure to a freeze solution, now needs below-freezing temperatures to survive. His weapon of choice is a freeze-blast gun, capable of freezing its target solid. In his first appearance, the gun could also produce a heat/incendiary beam.
