Fund and the Lignum Vitae Club. Nonetheless, when scholarly and popular works were written in the 1970s about the Black British presence in Britain, she was absent from the historical record, and went unrecorded by Dominican-born scholar Edward Scobie and Nigerian historian Sebastian Okechukwu Mezu. The centenary of her death was celebrated with a memorial service on 14 May 1981 and the grave is maintained by the Mary Seacole Memorial Association, an organization founded in 1980 by Jamaican-British Auxiliary Territorial Service corporal, Connie Mark. An English Heritage blue plaque was erected by the Greater London Council at her residence in 157 George Street, Westminster, on 9 March 1985, but it was removed in 1998 before the site was redeveloped. A "green plaque" was unveiled at 147 George Street, in Westminster, on 11 October 2005. However, another blue plaque has since been positioned at 14 Soho Square, where she lived in 1857. By the 21st century, Seacole was much more prominent. Several buildings and entities, mainly connected with health care, were named after her. She was, for example, the namesake of Seacole Way in Shrewsbury, part of the Copthorne Grange housing estate developed in 2011-12 on site of the former Copthorne Hospital, near the present Royal Shrewsbury Hospital. In 2005, British politician Boris Johnson wrote of learning about Seacole from his daughter's school pageant and speculated: "I find myself facing the grim possibility that it was my own education that was blinkered." In 2007 Seacole was introduced into the National Curriculum, and her life story is taught at many primary schools in the UK alongside that of Florence Nightingale. She was voted into first place in an online poll of 100 Great Black Britons in 2004 carried out by the website Every Generation. The portrait identified as Seacole in 2005 was used for one of ten first-class stamps showing important Britons, to commemorate the 150th anniversary of the National Portrait Gallery. British buildings and organisations now commemorate her by name. One of the first was the Mary Seacole Centre for Nursing Practice at Thames Valley University, which created the NHS Specialist Library for Ethnicity and Health, a web-based collection of research-based evidence and good practice information relating to the health needs of minority ethnic groups, and other resources relevant to multi-cultural health care. There is another Mary Seacole Research Centre, this one at De Montfort University in Leicester, and a problem-based
