WILDE, HENRY.

On Some Improvements in Electromagnetic Induction Machines.

London, Taylor and Francis, 1873. 8vo. Offprint, seperately paginated, with author presentation inscription to top of front wrapper ("Joseph Sidelbotham / with the Author's best regards"). Fine and clean. 8 pp. + 1 folded plate.

Scarce offprint issue, with a most interesting presentation inscription to one of the fathers of photography, of Wilde's paper on improvements of his electromagnetic induction machine introduced in 1866. Wilde discovered, independently of Werner von Siemens who is usually credited for the invention, the dynamo-electric machine. Despite Siemens being the one credited for the invention, Wilde was the first to publish a paper describing it; this was communicated to the Royal Society by Michael Faraday in 1866.

Joseph Sidebotham (1824-1882) was the first to practice photography in Manchester and of the most important local photographers in general. His interest was, however, not confined to photography; he was an amateur botanist, entomologist and astronomer. He was also a Fellow of the Royal Astronomical Society and lectured to the Mechanics Institute on astronomy and electro-magnetism.
