Heinrich Daniel Ruhmkorff (of Rühmkorff) (Hannover, 15 januari 1803 – Parijs, 20 december 1877) was een Duitse instrumentmaker die de vonkinductor (vaak als Ruhmkorff-inductor aangeduid) commercialiseerde.

Il padre era reggente di un ufficio postale ed Heinrich (uno dei 10 figli) terminate le scuole elementari dovette andare a lavorare presso un tornitore per non pesare sul bilancio famigliare. Viaggiò quindi per l'Europa, dapprima a Stoccarda, poi a Parigi, quindi a Londra, per perfezionare le sue conoscenze in meccanica, suo grande interesse. A Londra lavorò presso le officine di Brahama, famoso inventore e costruttore di serrature e più tardi di presse idrauliche, e nello stesso periodo conobbe i lavori di scienziati come Davy, Herschel, Faraday, Brewster. Nel 1839 si mise in proprio a costruire apparecchi di fisica, aprendo un laboratorio a Parigi, proprio di fronte alla Sorbona. Ciò gli permise di farsi apprezzare dai professori e ricercatori dell'università parigina; nel 1844 Melloni gli commissionò il banco da lavoro per le esperienze sul calore.A quarant'anni iniziò i lavori per la realizzazione della bobina che porta il suo nome. Intorno alla paternità del dispositivo sono sorte difficili discussioni, poiché nel 1836 l'americano Henry aveva costruito degli apparecchi per la scossa elettrica molto simili; tuttavia tali strumenti erano privi del condensatore derivato fra i punti nei quali avviene l'interruzione del circuito primario, applicato invece dal Ruhmkorff. La realizzazione del rocchetto gli valse nel 1855 la croce della Legion d'Onore durante l'Esposizione di Parigi. Nel 1864 vinse il premio Volta di 50.000 franchi che Napoleone III volle assegnare a chi avesse trovato la migliore applicazione della pila. Si occupò in particolare della polarizzazione rotatoria generata da un forte campo magnetico e di vari problemi di elettricità e magnetismo.Divenne celebre per l'invenzione del , più comunemente noto come rocchetto di Ruhmkorff, invenzione che all'epoca ebbe vasta risonanza in tutto il mondo scientifico.La possibilità di ottenere alte tensioni permise di eseguire interessanti esperienze sugli effetti della scarica elettrica nei gas rarefatti. Tale studio aprì una nuova fase nello sviluppo delle ricerche sulla natura delle cariche elettriche.che sulla natura delle cariche elettriche.

Ruhmkorff was born in Hanover. He changed the "ü" to "u" in his name when living abroad. After an apprenticeship with a German mechanic, he moved to England. Contemporaneous and extant biographies have made the assertion that he worked with the inventor Joseph Bramah, but this is unlikely since Bramah died in 1814. He may, though, have worked for the Bramah company. In 1855, he set up a shop in Paris, where he gained a reputation for the high quality of his electrical apparatus. Although Ruhmkorff is often credited with the invention of the induction coil, it was in fact invented by Nicholas Callan in 1836. Ruhmkorff's first coil, which he patented in 1851, utilized long windings of copper wire to achieve a spark of approximately 2 inches (50 mm) in length. In 1857, after examining a greatly improved version made by an American inventor, Edward Samuel Ritchie, Ruhmkorff improved his design (as did other engineers), using glass insulation and other innovations to allow the production of sparks more than 30 centimetres long. Ruhmkorff patented the first version of his induction coil in 1851, and its success was such that in 1858 he becomes the first recipient of the Volta Prize, 50,000 French franc award by Napoleon III for one of the most important discoveries in the application of electricity. He died in Paris in 1877. The Ruhmkorff lamps or 'Ruhmkorff's apparatus' mentioned in several of Jules Verne's science-fiction novels relied on induction coils but were not developed by Ruhmkorff.coils but were not developed by Ruhmkorff.
