Tinted lithograph by Leighton Bros after A Blaikley. Faraday is lecturing to an audience of distinguished guests including Prince Albert and his son. Michael Faraday (1791-1867) discovered the principles of the electric motor and dynamo. Faraday's great life work was the series 'Experimental Researches on Electricity' published over 40 years in 'Philosophical Transactions', in which he described his many discoveries including electromagnetic induction (1831), the laws of electrolysis (1833) and the rotation of polarised light by magnetism (1845).
