Anthony Stark was born on Long Island, the son of Howard Stark, a wealthy industrialist and head of Stark Industries, and Maria Stark. Tony is a boy genius, entering MIT at the age of 15 to study electrical engineering, and graduating summa cum laude. After his parents' accidental deaths in a car crash, he inherits his father's company. While observing the effects of his experimental technologies on the American war effort, Tony Stark is injured by a booby trap and captured by the enemy, who then orders him to design weapons for them. However, Stark's injuries are dire and shrapnel in his chest threatens to pierce his heart. His fellow prisoner, Ho Yinsen, a physicist whose work Stark had greatly admired during college, constructs a magnetic chest plate to keep the shrapnel from reaching Stark's heart, keeping him alive. Stark uses the workshop to design and construct in secret a suit of powered armor. Stark uses the armor to escape, although Yinsen dies during the attempt. Stark takes revenge on his kidnappers, then heads back to rejoin the American forces. Along the way he meets a wounded American Marine Corps helicopter pilot, James "Rhodey" Rhodes.
