Paul Crutzen Born 3 Dec 1933. Paul Josef Crutzen is a Dutch chemist who received the 1995 Nobel Prize for Chemistry for demonstrating, in 1970, that chemical compounds of nitrogen oxide accelerate the destruction of stratospheric ozone, which protects the Earth from the Sun's ultraviolet radiation. His work, published in 1970, that showed that the nitrogen oxides NO and NO2 react catalytically with ozone, thus accelerating the rate of ozone breakdown to O2 in the stratosphere. These nitrogen oxides are formed principally by decay of nitrous oxide (N2O) which originates from microbiological transformations in the soil. He shared the prize with chemists Mario Molina and F. Sherwood Rowland, who discovered in 1974 that manufactured chlorofluorocarbon gases also contribute to ozone depletion.
