Many years ago, Lewis Lang and his wife and children moved into a small home next to the Kent family in the suburbs of Smallville. During this time, his toddler daughter became friends with the Kent's adopted son, Clark. Lewis and Sarah Lang spent very little time at home however, as his archaeological research required him to travel all across the globe, excavating ancient ruins. During such trips, the Langs would ask Jonathan and Martha to watch over Lana for them, an act that invariably brought Clark no end of frustration.
On his sojourns, Lewis would occasionally discover the remains of a lost civilization or an ancient artifact that he would bring back home as a souvenir for Lana. He discovered that many of his gifts demonstrated remarkable properties, and it was not uncommon for select artifacts to contain an ancient riddle or curse.
- This version of Lewis Lang, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
