GROVE, SIR WILLIAM ROBERT English judge and man of science, was born on July I 1, 181 i at Swansea, South Wales. He went to Brasenose College, Oxford, and in was called to the bar at Lincoln's Inn. Grove occupied his leisure with scientific studies. His researches dealt very largely with electrochemistry and with the voltaic cell, of which he invented several varieties. One of these, the Grove gas-battery, which is of special interest, was based on his observation that a current is produced by a couple of platinum plates standing in acidulated water and immersed, the one in hydrogen, the other in oxygen. In 1846 he published his book on The Correlation of Physical Forces. In 1871 he was made a judge of the Common Pleas and remained on the bench till 1887. He died in London on Aug. I, 1896.
