Robert Chartham

Robert Chartham was the pseudonym of Ronald Sydney Seth (5 June 1911, England – 1 February 1985), a British writer who used the name Chartham for his activity as a sexologist and the name Seth for travel books and books about espionage.

As a child Seth was a chorister at Ely Cathedral and a King's Scholar at King's School, Ely. He was educated at Cambridge University.

Appointed Professor of Literature at the University of Tallinn, Seth returned to London at the start of World War II, joining the BBC and helping to start the Monitoring Intelligence Bureau. In 1941 he was commissioned into the RAF and in 1942 joined SOE. Parachuted into Estonia, he was captured by the Germans and trained by the Sicherheitsdienst as an agent for a mission to Britain. Seth spent most of the rest of the war as a "stool pigeon" in Oflag 79, but in April 1945 was entrusted with a message of peace by Himmler, which he carried to London via Switzerland.

Chartham's career included teaching and counselling in European universities, lecturing to British university students on "How to Enjoy Sex" and serving as a counsellor in his own London clinic.

He was an editorial consultant to Forum: The International Journal of Human Relations.

In the 1970s Seth lived in Malta with his second wife, Barbara McAdam Seth.
