Claud Cockburn

Francis Claud Cockburn ( ; 12 April 1904 – 15 December 1981) was a British journalist. His saying "believe nothing until it has been officially denied" is widely quoted in journalistic studies, but he did not claim credit for originating it. He was the second cousin, once removed, of the novelists Alec Waugh and Evelyn Waugh. He lived at Brook Lodge, Youghal, County Cork, Ireland.

In 1940 Cockburn's Security Service file said that "In 1939 he was a leading British Communist Party member and was said to be a leader of the Comintern in Western Europe". Provided by Wikipedia
