Cedric Allingham
June 27, 1922 – present
Birth place: Bombay, Bombay Presidency, British India
In fact a pseudonym by Surrey journalist <a href="https://en.wikipedia.org/wiki/Cedric_Allingham#Hoax_revealed">Peter Davies</a> and, most probably, Patrick Moore. His publishers claimed that Allingham was undergoing medical treatment in Switzerland, and then that he had died there in 1956.
