By the middle of the 18th century there were five voluntary hospitals in London (St Bartholomew's, Guy's, St Thomas', Westminster and St George's) which provided free medical care to those who could not afford it. However, none was located in the east of the city, where it could have served the comparatively impoverished and rapidly growing population there; this was the void that the London Hospital was to fill. The institution that was to become the Royal London Hospital was founded on 23 September 1740, when seven gentlemen met in the Feathers Tavern in Cheapside in the City of London to subscribe to the formation of an "intended new infirmary".
