William Joyce - the infamous nazi propagandist, Lord Haw-Haw - lived at 83 Onslow Gardens during 1938.
Born in New York in 1906 and from an Irish background, Joyce was active in the blackshirts during the thirties and at the outbreak of war he quickly crossed over to Germany, from where he soon began to broadcast nightly to Britain.
Joyce was not without talent - his imitations of Churchill were often very funny - but whether he genuinely had any impact on British morale is very much open to doubt.
After the war he was captured and put on trial. The trial lasted three days. The case centred on whether Joyce had a duty of allegiance to the King.
The prosecution argued that though he was born in America he held a British Passport. He left the UK on this passport and had the protection given to passport holders. As protection demands allegiance, Joyce broke this allegiance and committed treason.
Joyce was found guilty of treason and hanged in 1946 at the age of 39.
