"Here the world's problems were solved" - Whereabout in London is this plaque?

Question

I need to find out where this plaque is. One thing for sure - it's somewhere in London.

Answer 1

Don't know exactly but it would make sense to try all the obvious places.
Parlament
Downing street
St Paul's Cathedral
Leicester Square
even try Buckingham Palace.

Try asking the person who asked the question if it is in London or the city of West minister( the bit around Parlament), that would narrow it down.

I think you will just have to get on the train to London and have a look round these places.

Answer 2

I don't know the answer, but I have these suggestions to make.

1.One idea might be to contact English Heritage, an organisation that has responsibility for Blue Plaques (although these plaques are "So-and-so lived here" types). http://www.english-heritage.org.uk/server/show/nav.1494

2. The next possibility would be to contact the local authorities with responsibility for central London (which is where the plaque is likely to be):
a) City of Westminster, Environment & Planning; http://www.westminster.gov.uk/environment/
b) City of London, Environmental Services; http://www.cityoflondon.gov.uk/Corporation/about_us/departmental/depts.htm
c) Greater London Authority, Architecture and Urbanism Unit .http://www.london.gov.uk/mayor/auu/how_we_work.jsp

3. Then you might want to think about what kind of problems the plaque could refer to, and match organisations. Here are some possibilities.
a) Science -
i) The Royal Society; http://www.royalsoc.ac.uk/
ii) The Royal Institution of Great Britain; http://www.rigb.org/rimain/index.jsp
iii) the Royal Observatory, Greenwich; http://www.rog.nmm.ac.uk/
b) Humanitarian -
i) Oxfam; http://www.oxfam.org.uk/
ii) Save the Children; http://www.savethechildren.org.uk/
c) Engineering -
i) The Institution of Civil Engineers; http://www.ice.org.uk/homepage/index.asp
ii)The Engineering Institution; http://www.engineering-institution.org.uk/
d) Academia/Philosophy -
i) The University of London; http://www.london.ac.uk/
ii) Brunel University. http://www.brunel.ac.uk/

I hope this gets you on the right track.
