What did William Petty blue plaque do at The Lansdowne Club?

The Story

# William Petty at The Lansdowne Club Standing before 9 Fitzmaurice Place, you're gazing at the townhouse that became the intellectual and political headquarters of one of Britain's most progressive statesmen during the crucial years of the American Revolution. William Petty, the 1st Marquess of Lansdowne, made this Berkeley Square residence his London base during the 1770s and 1780s, transforming it into a salon where radical political thought flourished and where he harbored American independence sympathizers at considerable personal and political risk—a stance that cost him dearly in an era of patriotic fervor. Within these walls, Petty crafted his arguments for American self-governance, corresponded with Benjamin Franklin and other colonial leaders, and advocated for peace during a time when most of Parliament demanded military victory, ultimately becoming the Prime Minister who negotiated the treaty recognizing American independence. This address represents more than just a grand Georgian townhouse; it's where one man's conscience led him to oppose his own government, making Fitzmaurice Place a quiet monument to intellectual courage and the belief that empires could be redefined through negotiation rather than domination.
