Professor Clarence Cobalt

Professor Clarence Cobalt

The villainous quack who is the "proprietor" of the Cobalt Clinic, where unfortunate victims of "infantile paralysis and other forms of bone and joint malformations" are charged sky-high prices for worthless cures and medicinal pills that are in reality nothing but sugar. Cobalt and his accomplice Grafton are apprehended by Superman in July 1940 (Act No. 26). (TGSB)
