# Blue plaque

A blue plaque is a permanent sign installed in a public place in the United Kingdom, and certain other countries and territories, to commemorate a link between that location and a famous person, event, or former building on the site, serving as a historical marker.
The term is used in the United Kingdom in two senses. It may be used narrowly and specifically to refer to the "official" scheme administered by English Heritage, and for much of its history restricted to sites within Greater London; or it may be used less formally to encompass a number of similar schemes administered by organisations throughout the UK. The plaques erected are made in a variety of designs, shapes, materials and colours: some are blue, others are not. However, the term "blue plaque" is often used informally to encompass all such schemes.

## History

The "official" scheme traces its origins to that launched in 1866 in London, on the initiative of the politician William Ewart, to mark the homes and workplaces of famous people. The first such scheme in the world, it has directly or indirectly provided the inspiration and model for many others. The scheme has been administered successively by the Society of Arts (1866–1901), the London County Council (1901–1965), the Greater London Council (1965–1986) and English Heritage (1986 to date). It was initially focused on Greater London, although between 1998 and 2005, under a trial programme since discontinued, 34 plaques were erected elsewhere in England. The Levelling-up and Regeneration Act 2023 extended the scheme to the whole of England.
Many other plaque schemes have been initiated in the United Kingdom. Some are restricted to a specific geographical area, others to a particular theme of historical commemoration. They are administered by a range of bodies including local authorities, civic societies, residents' associations and other organisations such as the Transport Trust, the Royal Society of Chemistry, the Music Hall Guild of Great Britain and America and the British Comic Society.
There are also commemorative plaque schemes throughout the world such as those in Paris, Rome, Oslo, and Dublin; and in other cities in Australia, Canada, the Philippines, Russia, and the United States. These take various forms, and they are more likely to be known as commemorative plaques or historical markers.

## English Heritage scheme

The original blue plaque scheme was established by the Society of Arts in 1867, and since 1986 has been run by English Heritage. It is the oldest such scheme in the world.
After being conceived by politician William Ewart in 1863, the scheme was initiated in 1866 by Ewart, Henry Cole and the Society of Arts (now the Royal Society of Arts), which erected plaques in a variety of shapes and colours.
The first plaque was unveiled in 1867 to commemorate Lord Byron at his birthplace, 24 Holles Street, Cavendish Square. This house was demolished in 1889. The earliest blue plaque to survive, also put up in 1867, commemorates Napoleon III in King Street, St James's. Byron's plaque was blue, but the colour was changed by the manufacturer Minton, Hollins & Co to chocolate brown to save money. The first woman to be honoured with a plaque was the actor Sarah Siddons in 1876. The plaque, placed on her house in Marylebone, London, was retrieved when the house was demolished in 1905 and is now held in the Victoria and Albert Museum.
In total, the Society of Arts put up 35 plaques, fewer than half of which survive today. The Society only erected one plaque within the square-mile of the City of London, that to Samuel Johnson on his house in Gough Square, in 1876. In 1879, it was agreed that the City of London Corporation would be responsible for erecting plaques within the City to recognise its jurisdictional independence. This demarcation has remained ever since.
In 1901, the Society of Arts scheme was taken over by the London County Council (LCC), which gave much thought to the future design of the plaques. It was eventually decided to keep the basic shape and design of the Society's plaques, but to make them uniformly blue, with a laurel wreath and the LCC's title. Though this design was used consistently from 1903 to 1938, some experimentation occurred in the 1920s, and plaques were made in bronze, stone and lead. Shape and colour also varied.
In 1921, the most common (blue) plaque design was revised, as it was discovered that glazed Royal Doulton stoneware was cheaper than the encaustic formerly used. In 1938, a new plaque design was prepared by an unnamed student at the LCC's Central School of Arts and Crafts and was approved by the committee. It omitted the decorative elements of earlier plaque designs, and allowed for lettering to be better spaced and enlarged. A white border was added to the design shortly after, and this has remained the standard ever since. No plaques were erected between 1915 and 1919, or between 1940 and 1947, owing to the two world wars. The LCC formalised the selection criteria for the scheme in 1954.
When the LCC was abolished in 1965, the scheme was taken over by the Greater London Council (GLC). The principles of the scheme changed little, but now applied to the entire, much larger, administrative county of Greater London. The GLC was also keen to broaden the range of people commemorated. The GLC erected 252 plaques, the subjects including Sylvia Pankhurst, Samuel Coleridge-Taylor, and Mary Seacole.
In 1986, the GLC was disbanded and the blue plaques scheme passed to English Heritage. English Heritage erected more than 300 plaques in London. In January 2013 English Heritage suspended proposals for plaques owing to funding cuts. The National Trust's chairman stated that his organisation might step in to save the scheme. In the event the scheme was relaunched by English Heritage in June 2014 with private funding (including support from a new donors' club, the Blue Plaques Club, and from property developer David Pearl). Four members of the advisory panel resigned over this transmutation. Professor David Edgerton and author and critic Gillian Darley were concerned that the scheme had been "reduced to a marketing tool for English Heritage". The vice chair Dr Celina Fox and Dr Margaret Pelling stated that the scheme was "being dismantled and its previous achievements discredited".
In April 2015, English Heritage was divided into two parts, Historic England (a statutory body), and the new English Heritage Trust (a charity, which took over the English Heritage operating name and logo). Responsibility for the blue plaque scheme passed to the English Heritage Trust.
The 1,000th plaque, marking the offices of the Women's Freedom League, 1908–1915, was unveiled in 2023.
* Society of Arts plaque on Samuel Johnson's house in Gough Square, London (erected 1876). Many of the early Society of Arts and LCC plaques were brown in colour.
* London County Council bronze plaque in Canonbury Square, commemorating Samuel Phelps (erected 1901)
* London County Council plaque at 48 Doughty Street, Holborn, commemorating Charles Dickens (erected 1903)
* One of seven LCC Royal Doulton plaques with coloured laurel relief border erected in 1925; 41 Beak Street, Soho
* London County Council plaque at 100 Lambeth Road, Lambeth, commemorating William Bligh (erected 1952)
* Greater London Council plaque at 29 Fitzroy Square, Fitzrovia, commemorating Virginia Woolf (erected 1974)
* English Heritage plaque, at 22b Ebury Street, Belgravia, London, commemorating Ian Fleming (erected 1996)

### Criteria

To be eligible for an English Heritage blue plaque in London, the famous person concerned must:
* Have been dead for 20 years. Fictional characters are not eligible;
* Be considered eminent by a majority of members of their own profession; have made an outstanding contribution to human welfare or happiness;
* Have lived or worked in that building in London (excluding the City of London and Whitehall) 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.
With regards to the location of a plaque:
* Plaques can only be erected on the actual building inhabited by a figure, not the site where the building once stood, or on buildings that have been radically altered;
* Plaques are not placed onto boundary walls, gate piers, educational or ecclesiastic buildings, or the Inns of Court;
* Buildings marked with plaques should be visible from the public highway;
* A single person may not be commemorated with more than one blue plaque in London.
Other schemes have different criteria, which are often less restrictive: in particular, it is common under other schemes for plaques to be erected to mark the sites of demolished buildings.

### Selection process

Almost all the proposals for English Heritage blue plaques are made by members of the public who write or email the organisation before submitting a formal proposal.
English Heritage's in-house historian researches the proposal, and the Blue Plaques Panel advises on which suggestions should be successful. This is composed of 12 people from various disciplines from across the country. The panel is chaired by Professor William Whyte. Other members (as at September 2023) include Richard J. Aldrich, Mihir Bose, Andrew Graham-Dixon, Claire Harman, Gus Casely-Hayford and Amy Lame. The actor and broadcaster Stephen Fry was formerly a member of the panel, and wrote the foreword to the book Lived in London: Blue Plaques and the Stories Behind Them (2009).
Roughly a third of proposals are approved in principle, and are placed on a shortlist. Because the scheme is so popular, and because a lot of detailed research has to be carried out, it takes about three years for each case to reach the top of the shortlist. Proposals not taken forward can only be re-proposed once 10 years have elapsed.

### Manufacture

From 1923, soon after the standardisation of the design in 1921, the plaques were manufactured by Royal Doulton which continued their production until 1955. From 1984 until 2015 they were made by Frank Ashworth at his studio in Cornwall, and were then inscribed by his wife. From 1955 to 1985 the lettering for the plaques was designed in the Roman lettering style by Henry Hooper. Since 2015, the plaques have been made by Ned Heywood, a potter, at his workshop in Chepstow, Wales. Each plaque is made entirely by hand.

### Event plaques

A small minority of GLC and English Heritage plaques have been erected to commemorate events which took place at particular locations rather than the famous people who lived there.

### Outside London

In 1998, English Heritage initiated a trial national plaques scheme, and over the following years erected 34 plaques in Birmingham, Merseyside, Southampton and Portsmouth. The scheme was discontinued in 2005, although English Heritage continued to provide advice and guidance to individuals and organisations outside of London wanting to develop local schemes.
In September 2023 the Department for Culture, Media and Sport announced the reintroduction of a national scheme, with Historic England as the lead developer. From mid 2024, the public will be invited to submit nominations, with eligibility criteria including a minimum of 20 years having passed since the death of the nominee, who must have made a significant contribution to human welfare or happiness. At least one surviving building must be associated with the nominee in a form that they would have recognised and the building must be visible from the public highway. The first plaque in the scheme was unveiled in Ilkley, West Yorkshire on 23 February 2024, commemorating Daphne Steele, first Black matron in the National Health Service in 1964. On 24 May 2024, a blue plaque commemorating the childhood home of musician George Harrison in Liverpool was unveiled, and was referred to in the press as "Historic England's first official non-London blue plaque".

## Other schemes

The popularity of English Heritage's London blue plaques scheme has meant that a number of comparable schemes have been established elsewhere in the United Kingdom. Many of these schemes also use blue plaques, often manufactured in metal or plastic rather than the ceramic used in London, but some feature plaques of different colours and shapes. In 2012, English Heritage published a register of plaque schemes run by other organisations across England.
The criteria for selection varies greatly. Many schemes treat plaques primarily as memorials and place them on the sites of former buildings, in contrast to the strict English Heritage policy of only installing a plaque on the actual building in which a famous person lived or an event took place.

### London

The Corporation of London continues to run its own plaque scheme for the City of London, where English Heritage does not erect plaques. City of London plaques are blue and ceramic, but are rectangular in shape and carry the City of London coat of arms. Because of the rapidity of change in the built environment within the City, a high proportion of Corporation of London plaques mark the sites of former buildings.
Many of the 32 London boroughs also now have their own schemes, running alongside the English Heritage scheme. Westminster City Council runs a green plaque scheme, each plaque being sponsored by a group with a particular interest in its subject. The London Borough of Southwark started its own blue plaque scheme in 2003, under which the borough awards plaques through popular vote following public nomination: living people may be commemorated. The London Borough of Islington has a similar green heritage plaque scheme, initiated in 2010.
Other plaques may be erected by smaller groups, such as residents' associations. In 2007 the Hampstead Garden Suburb Residents Association erected a blue plaque in memory of Prime Minister Harold Wilson at 12 Southway as part of the suburb's centenary celebrations.
* Corporation of London plaque on the site of Lloyd's Coffee House in Lombard Street
* City of Westminster green plaque at 18 Cavendish Square, Marylebone, commemorating Josef Dallos, contact lens pioneer (erected 2010)
* Corporation of London plaque on the site of John Keats' birthplace
* City of Westminster green plaque commemorating Laura Ashley
* City of Westminster green plaque at the Savoy Theatre, the first public building in the world to be lit entirely by electricity when it was fitted with the incandescent light bulb developed by Sir Joseph Swan in 1881.

### Northern Ireland and the Republic of Ireland

In Northern Ireland, Belfast City Council and the Ulster History Circle are among a small number of groups administering blue plaques. Established in 1983, the Ulster History Circle has erected around 260. Its scope extends into the Republic of Ireland, covering all nine counties of Ulster, the northern province in Ireland. Elsewhere in the Republic, schemes are operated through local authorities and civic societies.

### Scotland

Historic Environment Scotland, the Scottish heritage agency, has previously operated a national commemorative plaques scheme but, as of 2023, this was inactive. Regional schemes are run by local authorities.

### Wales

Wales does not operate a national blue plaque scheme, although in 2022 Andrew RT Davies, leader of the Welsh Conservative Group in the Senedd, called for the introduction of a country-wide approach. Regional schemes are operated by local authorities such as Swansea and civic societies. The Purple Plaques scheme is a national scheme (across Wales) that aims to commemorate women whose lives have had a significant and long-lasting impact.

### Individual examples

* Blue plaque in Belfast commemorating Isabella Tod, founder of the Irish Women's Suffrage Society
* Blue plaque in Jedburgh commemorating John Ainslie, surveyor and cartographer
* Blue plaque in Rhiwbina Garden Village commemorating Iorwerth Peate, first director of St Fagans National Museum of History
* Blue plaque commemorating Tadhg Gaelach Ó Súilleabháin, poet, at Waterford County Waterford

### Thematic schemes

There also exist several nationwide schemes sponsored by special-interest bodies, which erect plaques at sites or buildings with historical associations within their particular sphere of activity.
* The Transport Trust's Red Wheel scheme erects red plaques on sites of significance in the evolution of transport.
* The Music Hall Guild of Great Britain and America erects blue plaques on sites associated with notable music hall and variety artistes, mainly in the London area.
