description Marion Donovan Overview

Marion Donovan (1917-1998) was an American inventor and entrepreneur who revolutionized childcare products with her innovations in diaper design. In 1951, she received a patent for the 'Boater,' a waterproof diaper cover made from nylon parachute cloth that featured snap closures instead of safety pins, preventing diaper rash and leakage more effectively than traditional rubber pants. Though major manufacturers initially rejected her concept, her invention laid the groundwork for the disposable diaper industry that would later be dominated by products like Procter & Gamble's Pampers, introduced in 1961.
