First edition of this early paper on the invention of the electromagnetic telegraph by
Luigi Magrini (1802-1868), professor of physics and applied mathematics. He gives
an overview of telegraphs and electrical telegraphs before concentrating on the
electromagnetic telegraph of his own invention, based on the understanding of the
link between magnetic and electric phenomena. He includes extensive technical
detail and calculations, and various details of his device are illustrated on the
engraved plates.
Magrini concludes with an interesting appendix in which he explains that his own
discovery preceded the experiments by Wheatstone and Steinheil by a few months,
and how while his publication was already at the printers the first news of
Wheatstone's and Steinheil's experiments on the same subject became public.
Wheatstone had his first patent granted in 1837, and together with Cooke is credited
with the first commercial use of the electromagnetic telegraph, whereas Steinheil is
generally acknowledged to have founded electromagnetic telegraphy in Austria.
