He was M.P. for Buckinghamshire, 1780-1784, Aldborough, 1790-1796, and Buckingham, 1796-1818, and was appointed Envoy Extraordinary to Vienna in 1794, and to Berlin in 1799. He was President of the Board of Control and First Lord of the Admiralty, 1806-1807. Grenville died on 17 December 1846 at Hamilton Place, Piccadilly. He bequeathed his collection of books to the British Museum, where it formed the Grenville Library.

J.H. Hessels is possibly Jan Hendrik Hessels (1836-1926).
