In the Elliot S! Maggin 1978 novel "", Jor-El is shown as having sent a navigation probe ahead of Kal-El's spaceship, in order to find a suitable foster parent on his new planet. In Kryptonian society, scientific achievement was a preeminent virtue, so Jor-El's probe was programmed to seek out the leading scientific mind on Earth, presumably to adopt Kal-El. The probe landed (in the early 1950s, although the date is non-specific) in Princeton, New Jersey, where it soon appeared outside the window of Albert Einstein and communicated its mission to him through telepathy, along with precise details of where Kal-El's rocket would land (near Smallville, Kansas), several days later. In the 2007 novel "The Last Days of Krypton" by Kevin J. Anderson, Jor-El is shown as a science hero who is respected and admired by all of the people of Krypton and has a standing offer of a place on the Council. Yet his clashing with this conservative Council over new discoveries supplies much of the tension in the book. General Zod and his two minions make a bid to take over Krypton, first posing as Krypton's saviours.
