SIR See also:WILLIAM See also:ROBERT See also:GROVE (1811-1896)  , See also:English See also:judge and See also:man of See also:science, was See also:born on the 11th of See also:July 1811 at See also:Swansea, See also:South See also:Wales . After being educated by private tutors, he went to Brasenose See also:College, See also:Oxford, where he took an See also:ordinary degree in 1832 . Three years later he was called to the See also:bar at See also:Lincoln's See also:Inn . His See also:health, however, did not allow him to devote himself strenuously to practice, and he occupied his leisure with scientific studies . About 1839 he constructed the See also:platinum-See also:zinc voltaic See also:cell that bears his name, and with the aid of a number of these exhibited the electric arc See also:light in the See also:London Institution, See also:Finsbury See also:Circus . The result was that in 1840 the managers appointed him to the professorship of experimental See also:philosophy, an See also:office which he held for seven years . His researches dealt very largely with electro-See also:chemistry and with the voltaic cell, of which he invented several varieties . One of these, the See also:Grove See also:gas-See also:battery, which is of See also:special See also:interest both intrinsically and as the forerunner of the secondary batteries now in use for the " storage " of See also:electricity, was based on his observation that a current is produced by a couple of platinum plates See also:standing in acidulated See also:water and immersed, the one in See also:hydrogen, the other in See also:oxygen . At one of his lectures at the Institution he anticipated the electric See also:lighting of to-See also:day by See also:illuminating the See also:theatre with incandescent electric lamps, the filaments being of platinum and the current supplied by a battery of his nitric See also:acid cells . In 1846 he published his famous See also:book on The Correlation of See also:Physical Forces, the leading ideas of which he had already put forward in his lectures: its fundamental conception was that each of the forces of nature—light, See also:heat, electricity, &c.—is definitely and equivalently convertible into any other, and that where experiment does not give the full See also:equivalent, it is because the initial force has been dissipated, not lost, by See also:conversion into other unrecognized forces . In the same See also:year he received a Royal See also:medal from the Royal Society for his Bakerian lecture on " Certain phenomena of voltaic ignition and the decomposition of water into its constituent gases." In 1866 he presided over the See also:British Association at its See also:Nottingham See also:meeting and delivered an address on the continuity of natural phenomena . But while he was thus engaged in scientific See also:research, his legal See also:work was not neglected, and his practice increased so greatly that in 1853 he became a Q.C .

One of the best-known cases in which he appeared as an See also:

advocate was that of See also:William See also:Palmer, the See also:Rugeley poisoner, whom he defended . In 1871 he was made a judge of the See also:Common Pleas in See also:succession to See also:Sir See also:Robert See also:Collier, and remained on the See also:bench till 1887 . He died in London on the 1st of See also:August 1896 . A selection of his scientific papers is given in the See also:sixth edition of The Correlation of Physical Forces, published in 1874 .
