Mark Olsen

Jimmy Olsen's long-lost father.

An archaeologist, Mark Olsen is washed downstream after a train wreck kills his wife and leaves his son Jimmy orphaned. Suffering from amnesia, Mark Olsen journeys to Mexico with another archaeologist, Hal Rand. When Olsen takes ill, Rand assumes him dead and return to Metropolis, leaving his friend to be nursed back to health by the Mexican Indians who worship Olsen as "Kukulkan, the white serpent of the Mayans." When Professor Lewis Lang presents Superman with evidence that Olsen is alive, Superman, Jimmy, and Hal Rand journey to the Yucatan and rescue him. After a tearful reunion, Mark Olsen settles back into life in Metropolis, living in a mansion purchased with Mayan treasure (SPJO No158, Jun 1973: "The Jaws of the Jaguar").
