Frank Sherwood Rowland

Frank Sherwood Rowland was a prominent American chemist known for his groundbreaking research on the effects of chlorofluorocarbons (CFCs) on the ozone layer. Along with his assistant Mario Molina, he published a pivotal paper in 1974 that linked CFCs to the depletion of the ozone layer, leading to significant global policy changes, including the Montreal Protocol in 1987. For their contributions to atmospheric chemistry, Rowland, Molina, and Paul Crutzen were awarded the Nobel Prize in Chemistry in 1995.
