American Crusader

Arch Masters was a professor who taught at Grand University somewhere in the eastern United States. A colleague created a device called an atom smasher, but the initial test went awry when Masters, preoccupied in his thoughts went into the room where the device was being used. He was bathed in atomic radiation but instead of killing him, the accident endowed him with various superhuman abilities such as strength, speed, and invulnerability. After his sister, and brother in law were murdered and his niece was attacked, he went out and confronted the attacker and hospitalized him. After that, he used his powers to fight crime as the American Crusader.
