John Battiscombe "
J. B."
Gunn (13 May 1928 – 2 December 2008), known as
Ian or
Iain, was a British
physicist, who spent most of his career in the United States. He discovered the Gunn effect, which led to the invention of the
Gunn diode, the first inexpensive source of
microwave power that did not require
vacuum tubes. He was born John Battiscombe Gunn, but only used that name in legal documents.
