Sir William R. Grove, by Lock and Whitfield, 1878
Sir William Robert Grove, (11 July 1811 – 1 August 1896) was a Welsh judge and physical scientist. He anticipated the general theory of the conservation of energy, and was a pioneer of fuel cell technology. He invented the Grove voltaic cell. He took a considerable interest in photographic science during the 1840s. In 1841 he experimented (with some collaboration from J. P. Gassiot) at the London Institution with daguerreotype plates for photomechanical printing. A paper on this ‘voltaic process for etching daguerreotype plates’ was read at a meeting of the London Electrical Society on 17 August 1841 and the prints he displayed there ought to, he suggested, have been inscribed ‘drawn by Light and engraved by Electricity’. He also attended to the annual meeting of the British Association for the Advancement of Science at York in 1844 and described experiments using nitric acid to obtain direct–positive calotype prints.
