He joined International PEN in 1962 and served first as general secretary and later as vice-president for seven years during the 1970s, rescuing the organisation from financial failure; he also secured the future of the Arts Theatre Club in London in 1946. He prospered as an entrepreneur with a facial product called Yeast Pac, with several partners. In his obituary in The Guardian newspaper, Elstob was said to be: ...one of those people born in the wrong century. With his charm and audacity, his passion for travel, and his love of risk-taking and financial gambles, he would have been more at home in the reign of Elizabeth I.

Kostov, John Kerrigan, Klaus Konrad, and Leo Kessler.

Keen to be in on the wartime action, Whiting was attached to the 52nd Reconnaissance Regiment and by the age of 18 saw duty as a sergeant in France, Holland, Belgium and Germany in the latter stages of World War II. While still a soldier, he observed conflicts between the highest-ranking British and American generals which he would write about extensively in later years. After the war, he stayed on in Germany completing his A-levels via correspondence course and teaching English before being enrolled at Leeds University reading History and German Language. As an undergraduate he was afforded opportunities for study at several European universities and, after gaining his degree, would go on to become an assistant professor of history. Elsewhere, Whiting held a variety of jobs which included working as a translator for a German chemical factory and spells as a publicist, a correspondent for The Times and feature writer for such diverse magazines as International Review of Linguistics, Soldier and Playboy. His first novel was written while still an undergraduate, was published in 1954 and by 1958 had been followed by three wartime thrillers. Between 1960 and 2007 Charles went on to write over 350 titles, including 70 non-fiction titles covering varied topics from the Nazi intelligence service to British Regiments during World War II. One of his publishers, Easingwold-based Rupert Smith of GH Smith & Son said he was a quiet man and prolific writer. "He's one of a band of forgotten authors because he sold millions of copies and still, up to his death was doing publishing deals.He was the kind of man who was very self-effacing, one of Britain's forgotten authors, still working at 80 years of age, with his nose down and kicking out books." Charles Henry Whiting, author and military historian died on July 24 2007, leaving his wife and son.
