The Ken Burns documentary on Benjamin Franklin airing this week in the USA covers the many years Franklin spent living in and around London, and how famous and infamous he was among Londoners - so I'm wondering what the best places to visit are that involve Franklin's activities there. --->Is there a lightning rod collection at the V&A? Are there recreations of his furnished rooms? That kind of thing.
I have previously pointed out the address in Paris where the treaties settling the (sort of) revolutionary war were signed, and the memorial markers in Nice where Jefferson visited and so on, so why not also check out the Ben Franklin locales in London?
