The Brown Bear pub was present by 1793 and was re-built in 1830. At 89 Leman Street in 1839, 1841 and 1848; and at 77 Leman Street in 1856 & 1871 census. It was still a pub in 2008, at 139 Leman street; and the building still exists in 2014, maybe even now.
My pub history site notes records of 1802, when Mr Carter was noted in the old bailey proceedings; and many other licensees, including Daniel Zuschlag in the 1880’s, Jacob Schaumloeffel just prior to the first world war, Herbert William Taylor Wells in the 1930’s and Annie Fowler in the 1940’s and 1950’s, etc etc.
That’s it really, I don’t see why wiki should be the top entry for this pub when they have little detailed research on it. Here it is.
