Dr. Cornelius, one of the senior scientists for the Weapon X program, Doctor Abraham was employed by the mysterious Professor Thorton. Some time after World War II, Wolverine was taken in by the project and doctor Abraham was assigned with the task of perfecting and using a technique that would bond the indestructible alloy adamantium to human bone cells. This adamantium-bonding process was first created by Lord Dark Wind, but was only put into use after being perfected by doctor Abraham when he succeeded in bonding Wolverine's skeleton with adamantium, after which Wolverine was indoctrinated into the Weapon X assassin program.
