Origin
American metallurgist Dr. Myron MacLain was contracted by the U.S. Government to develop a new alloy for tank production during World War II.  MacLain's first experiments resulted in combining the exotic metal Wakandan Vibranium with a steel alloy which he shaped into the form of a disk, but he was unable to replicate the process.  He turned his experiment over to the military which gave it to Captain America to use as his shield.

After the war Dr. MacLain continued his experiments eventually achieving success in creating an even more resilient alloy which he dubbed Adamantium.
