Hang on. Don't you have to have been dead 20 years to have a blue plaque? Given the name, and the unusual year of death, we at first suspected this building on Berwick Street to be the abode of a certain Gallifreyan national. Sadly, it's not the famous Timelord, but a Soho tailor of the same name. The Willy Wonka lookalike has outfitted such luminaries as Sir Menzies Campbell and Take That.
Given that he claims to have experience of the next 35 years or so, his suits will no doubt stay considerably ahead of fashion.
