‎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.
