According the US State Department's travel information web site, travel.state.gov, "A visa is not required for tourist or business visits to the UK of less than six months in duration." For other situations, see the web site for more information.
That depends, of course, on the purpose of the visit. For a short visit for purposes of tourism or one of making business contacts, presentations, etc. probably not. For purposes of setting up residence, conducting employment, studying or establishing business then one needs the necessary student, work and/or residence permits. Official visitors need to be sponsored by their organisations, UNO, NATO, etc. Check out the website of the British Embassy or High Commission of your country of citizenship or residence for up to date information.
