Edward Appleton (1892-1965)

Appleton was the British physicist who discovered one of the layers of ionized particles that reflect radio waves in ionosphere.
This layer was often known as the Appleton layer, but is now understood to be two separate layers that are known as F1 and F2.
Appleton's work in atmospheric physics was important to the development of radar, and in 1974 he was awarded the Nobel prize for Physics.
