Antoine Lebec (SEY 2258 - 2307?) was a navjumper most notable for his discovery of the Nul system in 2290.
Born on Earth (Sol III), he was inspired to become an explorer after Nick Croshaw discovered the Croshaw system in 2271. He completed pilot training in 2277, but wasn't able to afford his own spacecraft until 2282, when he won a land and mineral rights lottery to a plot on Angeli (Croshaw II) that sat on a natural vein of copper. This source of revenue enabled him to purchase a ship and become a full time navjumper.
When he discovered the Nul jump point, he reported that he had found "nul" during his initial visit there, thus giving the system its name. He disappeared while investigating the outskirts of Nul in 2307. Historians speculate that he may have perished while attempting to navigate the Nul-Caliban jump point that would later be discovered by Ashleigh Gonn.
