The diminutive Albert Pratt was a sophomore at Calvin College where he was often referred to by fellow students as "Atom Al."

In love with a local debutante named Mary James, Pratt was rebuked after his negotiations for a prom date were interrupted by a mugger - who easily beat Pratt and stole James' purse and jewelry. Humiliated and dejected Pratt headed home in misery when he was approached by a panhandler. Despite his recent turmoil Pratt showed the destitute beggar sympathy and bought him dinner. In the course of conversation, it was revealed that the beggar was former heavyweight boxer Joe Morgan. Sharing the unfortunate events of earlier in the evening, Morgan offered to train Pratt and help him build his strength. Using some inheritance Pratt provided Morgan with housing in exchange for his services as trainer, using every available hour to hone his skills and build his strength. In a few months' time Pratt completed his intense training and turned his label which was meant to denote weakness into a modern meaning of power by dubbing himself the mighty Atom.
