Airy, the new Secretary of Trinity House PH Berthon, the Birmingham glassmaker JT Chance, the French chemist and politician JBA Dumas, the Assistant Secretary of the Board of Trade TH Farrer, the German mathematician Julius Plücker, the Cambridge trained mathematical natural philosophers James Clerk Maxwell, George Gabriel Stokes and William Thomson, Faraday's colleague at the Royal Institution John Tyndall and the Swiss chemist Christian Schoenbein whose daughter died while in London.
