Blue plaques are placed around England:
In order to be eligible for an English Heritage blue plaque, a figure must have been dead for twenty years or have passed the centenary of their birth. Nominated figures must be considered eminent by a majority of members of their own profession; have made an outstanding contribution to human welfare or happiness; have resided in a locality for a significant period, in time or importance, within their life and work; be recognisable to the well-informed passer-by, or deserve national recognition. In cases of foreigners and overseas visitors, candidates should be of international reputation or significant standing in their own country. EH plaques can only be erected on the actual building inhabited by a figure, not the site where the building once stood; buildings marked with plaques should be visible from the public highway; unless a case is deemed exceptional, a single person may not be commemorated with more than two plaques nationwide.
