Dr. Franklin Storm, the father of Susan Storm and Johnny Storm, was an accomplished surgeon. While driving to a dinner being held in his honor, one of the tires in his car blew out and the car sweved off the road and crashed, fatally injuring his wife Mary. Dr. Storm operated on Mary Storm in a desperate attempt to safe her life, but he was unable to save her and he blamed himself for her death. He gave up his career and turned to gambling, eventually borrowing money from a loan shark. When Dr. Storm was unable to pay, a criminal sent by the loan shark threatened Storm and his children, and Storm grappled with the man. During the fight, the man shot himself and Storm was sent to prison for 20 years for manslaughter. Upon his request, Susan did not visit him while in prison and told Johnny that he was dead.
Susan and Johnny subsequently gained superhuman powers and became members of the Fantastic Four. Franklin Storm escaped from prison early in the Fantastic Four's career, and when he learned that Susan had been seriously injured while escaping from the Mole Man's lair, he came out of hiding and operated on her, saving her life. After the operation, Dr. Storm was returned to prison.
Shortly thereafter, the Super-Skrull came to Dr. Storm in his cell, and used his shapechanging powers to take Storm's appearance. Storm, meanwhile, was teleported to the Skrull homeworld and held captive there. The disguised Super-Skrull took on the name "the Invincible Man", claiming to be Dr. Storm with newly-acquired superhuman powers, and broke out of prison. The Super-Skrull confronted the Fantastic Four, hoping to demoralize them by tricking them into thinking that Dr. Storm was attacking them. Reed Richards was able to recognize the impostor and forced the Skrull leaders to exchange their agent for the real Dr. Storm.
The Skrulls attached a concussive energy beam projector to Dr. Storm's chest; the projector was set to go off the moment he saw the Fantastic Four. When Storm appeared, he warned the heroes to stay away and rolled over on the floor, taking the full force of the deadly concussive blast on himself.
Susan Storm later named her son Franklin after her father in honor of his memory.
