In The Last Son of Krypton, Superman is born on an alien world to a technologically advanced species that resembles humans. Shortly after he is born, his planet is destroyed in a natural cataclysm, but Superman's scientist father foresaw the calamity and saves his baby son by sending him to Earth in a small spaceship. The ship is too small to carry anyone else, so Superman's parents stay behind and die. The earliest newspaper strips name the planet "Krypton", the baby "Kal-L", and his biological parents "Jor-L" and "Lora"; their names were changed to "Jor-el", and "Lara" in a 1942 spinoff novel by George Lowther. The ship lands in the American countryside, where the baby is discovered by the Kents, a farming couple.
