The ozone layer was discovered in 1913 by the French physicists Charles fabry and Henri bussion. Its properties were explored in detail by the British meterologist G.M.B dobson, who developed a simple spectrophoto meter that could be used to measure stratospheric ozone from the ground. Between 1928 and 1958 Dobson established a worldwide network of ozone monitoring stations, which continue to operate to this day. The Dobson unit a conveninent measure of the amount of ozone over head is named in his houour.
