      For his son and Superman's father, see Jor-El II (Earth-One).

Jor-El was a scion of the House of El, the father of Jor-El II and grandfather of Superman.


Like many in his family, Jor-El was a respected scientist and a patriarch of the noble House of El. To the amazement of his colleagues, he succesfully created an experimental rocket-ship capable of traveling through hyperspace. Jor-El personally embarked upon a one-man journey to the Sol System wherein he discovered a small habitable world known as Earth. Returning to Krypton he kept extensive notes concerning Earth and passed them down to his first son, Jor-El II. It was the elder Jor-El's readings of Krypton's core which also drew his son to conclude from his notes that Krypton was doomed. Jor-El the First was stricken comatose by a marauding Ice-Bird while visiting the Kryptonian South Pole with his son to show him a hidden starship, which had been sequestered in a frigid cavern by ancient Krull colonists. It was after Jor-El II made his plea to the Science Council and was rejected that Jor-El I opened his eyes one final time, to tell his son of the ship and the cave before expiring.


However, Jor-El II did not have the resources or time to locate the Krull ship by himself and use it to save the Kryptonian race. After Jor-El II succeeded in his election to the Science Council, Jor-El I's assistant Mar-Ko contacted him to reveal his independent discovery of the Krull ship. Jor-El II took the ship on its test-flight, but by a freak accident, the ship collided with an experimental rocket launched into space illegally by Jax-Ur. This had the effect of altering the rocket's flight path so that it struck and destroyed Krypton's moon of Wegthor, a crime for which Jax-Ur was imprisoned in the Phantom Zone. The Krull ship was sufficiently damaged that it blew apart shortly after it landed back upon Krypton's surface.[1] While his discovery of the Krull ship came to naught, Jor-El I's account of Earth inspired Jor-El II to send his own child Kal-El to the planet when the end came.


  • This version of Jor-El I (Earth-One), including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
