Dr. Erskine

Doctor Abraham Erskine was a scientist who created the original Super Soldier Serum and was forced to use a preliminary version to transform Johann Schmidt into the Red Skull. Fleeing to the United States of America, Erskine joined the Strategic Scientific Reserve where he managed to perfect his serum, using it on Steve Rogers shortly before being assassinated by HYDRA.

Erskine was a master scientist of integrity. He understood the importance of compassion for the weak, refusing to accept Gilmore Hodge as a candidate for Project Rebirth because of how the latter treated Steve Rogers in boot camp, referring to him as "a bully" despite his physical qualifications. His decision to elect Rogers for the Super Soldier operation was solidified when Rogers selflessly ran to cover a grenade, which was, in reality, a dud.
