The Gells, Kaye, Banks, Adams, and the Dukes of Devonshire and Bedford were all establishment figures whose hostility to the radicals of the Lunar and Derby Philosophical Societies intensified in the British reaction to the French Revolution. Bennet found it increasingly necessary to take sides, signing the Gells' petition against Jacobinism in 1795. Bennet's scientific work ends around this date, possibly from ill-health but also possibly from his inability to resolve the tensions among his erstwhile supporters.[1]
