Mr. Ohm
From superman.nu: Supermanica
Mr. Ohm
A cunning criminal mastermind who carries out a series of spectacular armored-car robberies by using a so-called "flying electro-magnet" --an airplane, wrapped in coils of heavy electric wire, with a giant magnet hanging suspended from its fuselage --to literally snatch the armored vehicles off the road and carry them through the air to his hideout. Mr. Ohm and his henchmen are apprehended by Superman in March-April 1948 (S No. 51/2" "The Magnetic Mobster!").
