If you're going to quote wikipedia do so fully - otherwise you may as well go back to who first jotted down the physics and properties of EM radiation. The first cavity magnetron was a German development and the first practical high power cavity (not pole, cavity) magetrons were developed by GEC here in the UK. Britain gifted an example with full plans to the U.S. as part of the Tizard mission.
