Fort Knox
A United States Army reservation, located approximately 35 miles south of Louisville, Kentucky, which is the site of the principal gold bullion depository of the U.S. government.
In June 1940 an airplane en route to Fort Knox with a valuable gold shipment is hijacked by the villain Medini (Act No. 25).
In August 1943, during a period when he is suffering from temporary amnesia and under the influence of the evil Professor Praline, Superman tunnels his way into the subterranean vaults at Fort Knox --referred to in this text as Fort Blox-- in order to help Praline and his henchmen loot the Federal gold reserve of $20,000,000,000 in gold bullion (Act No. 63: "When Stars Collide!").
In August 1960 Lex Luthor dupes Hercules into helping him loot Fort Knox and carry off a ton of gold, but Superman apprehends Luthor soon afterward with some friendly assistance from Hercules (Act No. 267: "Hercules in the 20th Century!").
Superboy once accidentally changes all the gold in Fort Knox to lead by focusing too intently with his X-Ray vision. In order to replace the bullion, he is forced to live under the earth and gradually find new deposits to make new gold bars. (SB No. 59/1, Sep 1957: "Superboy's Underground Exile")
