Marion
Meaning
a form of Mary; famously borne by Marion Donovan, inventor of the modern disposable diaper
Immortalized by Marion Crane in Psycho (1960).
The story
Marion left medieval France as an affectionate pet form of Mary and has been comfortably unisex ever since: John Wayne was born Marion Morrison, and generations of American boys were named, it is often said, in honor of Francis Marion, the Revolutionary War's elusive Swamp Fox. Its place among the inventors belongs to Marion Donovan, who in the late 1940s, weary of soaked cloth diapers and rubber pants that chafed, cut apart a shower curtain and sewed the Boater, a waterproof diaper cover she patented and sold to delighted parents, then spent years championing the fully disposable diaper that manufacturers at first waved away. She was born in 1917, almost exactly when Marion stood at its American peak; the name slid gently downward from midcentury and now reads as quiet vintage, a soft three syllables with a surprising amount of iron in the biography.
