Professor Kimda. A brilliant Kryptonian scientist, as well as the former college roommate of Superman's father Jor-El, and who was residing in the bottle city of Kandor when it was abducted by the space villain Brainiac, and then shrunk and placed in a bottle aboard Brainiac's space-craft prior to the destruction of the planet Krypton. Much like the rest of the city, Kimda continued his way of life as best he could within the bottle, (supposedly continuing to conduct experiments in his laboratory). When Superman discovered the city during his first battle with Brainiac - when he was shrunk to a small size aboard Brainiac's space-craft and forced to hide - it was Kimda who befriended him and explained how Kandor had come to be in it's current predicament. With Kimda's help, and with the use of a powerful rocket and a Metal-Eating Mole from Kandor's zoo was Superman able to break free from the bottle. Restoring Metropolis and other Earth cities to their normal size on his adopted homeworld (after being shrunk by Brainiac), Superman was left with a dilemna as to whether to use the last of energy from Brainiac's Hyper-Ray to restore himself or Kandor to normal size. However, using a small rocket of his own, Kimda ultimately decided this for him by using the ray on Superman because after all, Kandor "could not let Earth be deprived of it's greatest super-hero!".
