Born February 3 circa 1928, Natalia "Natasha" Romanova was apparently orphaned as a child when she was trapped in a burning building during an early attack on Stalingrad by enemy forces. Ivan Petrovitch Bezukhov, a Soviet soldier, found Natasha in the inferno and rescued her. Although Ivan kept a close eye on Natasha as she grew, by the late 1930s she had attracted the attention of Soviet intelligence, which began her training.
