Plaque commemorating Francis Barber, servant, friend and heir of Samuel Johnson

Samuel Johnson was the brains behind Johnson’s Dictionary of the English Language (1755). He shared his home with Francis Barber, a former Jamaican slave. He became like a surrogate son, and eventually his heir.
This plaque commemorating their friendship is mounted at DrJohnson's House in Gough Square, London, where the pair lived together between 1752 and 1756.
The plaque was created by a BBC History team and is one of twenty placed around the world by the series Black and British: A Forgotten History.
