Today's Fact
Checked against independent sources — the issues are cited below.
Long before the Cloak of Levitation, Stephen Strange owed his entire career to his younger sister. At eleven years old he rushed to help Donna Strange after she hurt herself roller skating on the family farm in Nebraska, and tending to her injury gave him his first taste of medicine. Eight years later the debt turned into a wound: home on vacation at nineteen, Stephen went swimming with Donna, she was seized by a cramp, and she drowned while he searched for her in desperate vain.
Stephen counted her death as his personal failure, and the guilt quietly poisoned the idealism that had drawn him to medicine. He rocketed through medical school and into a lucrative neurosurgical residency, yet bereavement upon bereavement — his mother Beverly's death among them — left him distant, fee-obsessed and so unable to face another family loss that he refused to visit his father Eugene's deathbed. The hands that would one day weave the mystic arts first learned helplessness in a Nebraska lake.
Remarkably, Donna herself reached print decades after her brother did. Stephen had headlined stories since Strange Tales #110 (1963), but Donna's first official comics appearance did not arrive until Doctor Strange, Sorcerer Supreme #45 (1992), when Marvel finally put the sister from his handbook history onto the page. The Sorcerer Supreme's origin is usually told as arrogance punished by a car crash; underneath it sits an earlier, quieter catastrophe that no spell in the Book of the Vishanti was ever cast to undo.
Why It's Obscure
The most powerful sorcerer on Earth started out as a boy who could not save one swimmer — and he has been keeping score ever since.
