Sydney Chapman
Sydney Chapman (Manchester, 29 januari 1888 - Boulder, 16 juni 1970) was een Brits wiskundige, astronoom en geofysicus. Chapman wordt gezien als de man die in 1930 het fotochemische mechanisme uitwerkte waaruit de ozonlaag voortkwam. Chapman leed aan depressies, maar bleek desondanks productief. In 1949 kreeg Chapman de Gold Medal van de Royal Astronomical Society en hij ontving de Copley Medal van de Royal Society in 1964. Lees meer op Wikipedia
