• The greatest English scientist, who devoted himself to at¬mospheric physics, using mainly radio techniques. • In 1924 proved the existence of the layer in the upper atmosphere now called the ionosphere. • Invented the method called “frequen¬cy-modulated radar”, which led to a great development of radio research. • In 1926 discovered a further atmos¬pheric layer 150 miles above ground, which reflects short waves round the earth. • In 1941 was knighted for the develop¬ment of radiolocation.
