He died at a conference of the British film industry in London in 1921 and is buried in Highgate Cemetery.

6) B: From 1737, the time of the first Prime Minister Robert Walpole's Theatrical Licensing Act, until 1968, all plays had to be licensed by the Lord Chamberlain's office before they could appear on a London stage. Three plays produced by the Royal Court in 1968, John Osborne's A Patriot for Me and Edward Bond's Saved and Early Morning, were refused permission to be performed at all.

It is thought that the street is named after a house built in 1612 on what was then open country to the west of the city by a wealthy tailor named Robert Baker.
