George John Singer (1786–1817) was an English early pioneer of electrical research, noted for his publications and for lectures delivered privately and at the Russell Institution.
[1] Singer built, almost unassisted, a large room at the back of his mother's house in Prince's Street, Cavendish Square, where he gave courses of lectures on electricity and kindred subjects.
[2] Singer published Elements of Electricity and Electro-chemistry, London, 1814, a work of considerable contemporary importance, which was translated into French (Paris, 1817), into Italian (Milan, 1819), and into German (Breslau, 1819).
He also contributed several papers to the Philosophical Magazine from 1813 to 1815, of which a list is given in Ronalds's Catalogue of Books on Electricity, Magnetism, &c.[2] Singer made almost the whole of his apparatus himself, and introduced several enhancements.
A key feature was a new mode of insulating the wire connected to the leaves through the cap of the bottle, which he announced in 1811 and described in his book.
