Politician and inventor of fireproofing systems. Born in Bath, he moved to London where he met and became close friends with Benjamin Franklin. As an MP, he represented Kingston-upon-Hull and became an opponent of the war with America, and the African slave trade. He devised a system of fire-proofing buildings by inserting metal plates between the floors. At one of his demonstrations, King George III and Queen Charlotte are said to have taken breakfast on the upper floor of his house while a fierce fire raged below! Died at his home in Belvedere, Lansdown, Bath.
