Crutzen is an Dutch chemist who shares the 1995 Nobel Prize in Chemistry with F. Sherwood Rowland and Mario J. Molina for their research on the ozone layer. Rowland and Maria discovered that man-made chlorofluorocarbons (CFCs) were a major contributor to the destruction of ozone in the atmosphere. Crutzen's contribution was the discovery that nitrogen oxide contributes to the depletion of the ozone layer. Their discoveries led to the banning of CFCs in general use.
