Robert Baden Powell:Blue Plaque 9 Hyde Park Gate, Kensington Robert Baden-Powell, 1st Baron Baden-Powell - Wikipedia
Referring tp Robert Baden-Powell as "Lord Robert" purports that he was a younger son of a senior peer, which he was not. He was a peer of the first creation in his own right. He may be described as "Robert Baden-Powell", "Lord Baden-Powell", "Robert, Lord Baden-Powell", even "Lord (Robert) Baden-Powell", but NEVER "Lord Robert Baden-Powell".
Took this today, didn't see it last time ? On the above photograph of the windmill, you can just see this plaque on the lower left side, upon the chimney stack.
