"The word ""dynamo"" (from the Greek word dynamis (δύναμις), meaning force or power) was originally another name for an electrical generator, and still has some regional usage as a replacement for the word generator. The word ""dynamo"" was coined in 1831 by Michael Faraday, who utilized his invention toward making many discoveries in electricity (Faraday discovered electrical induction) and magnetism. The original ""dynamo principle"" of Wehrner von Siemens or Werner von Siemens referred only the direct current generators which use exclusively the self-excitation (self-induction) principle to generate DC power. The earlier DC generators which used permanent magnets were not considered"
"Dynamite Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, and patented in 1867. It rapidly gained wide-scale use as a more powerful alternative to black powder. Today dynamite is mainly used in the mining, quarrying, construction, and demolition industries. Dynamite is still the product of choice for trenching applications, and as a cost-effective alternative to cast boosters. Dynamite is occasionally used as an initiator or booster for AN and ANFO explosive charges. Dynamite was invented by Swedish chemist Alfred"
"Henry Wilde (engineer) Henry Wilde (1833 – 28 March 1919) was a wealthy individual from Manchester, England who used his self-made fortune to indulge his interest in electrical engineering. He invented the dynamo-electric machine, or self-energising dynamo, an invention for which Werner von Siemens is more usually credited and, in fact, discovered independently. At any rate, Wilde was the first to publish, his paper was communicated to the Royal Society by Michael Faraday in 1866. The self-energising dynamo replaces the permanent magnets of previous designs with electro-magnets and in so doing achieved an enormous increase in power. The machine was"

The invention of the dynamo in 1867 led to a switch from Siemens' previous strength in light-current products to heavy-current products and processes. The world's first modern high-voltage power station was opened in 1891, Deptford East. Designed in 1887 by 23-year-old former Siemens' apprentice Sebastian de Ferranti it was erected by the London Electricity Supply Corporation on the Thames bank at Deptford Creek, two and a half miles west of Siemens' Woolwich site. Berlin was anxious that the London business should break its reliance on the"

"The first dynamo based on Faraday's principles was built in 1832 by Hippolyte Pixii, a French instrument maker. It used a permanent magnet which was rotated by a crank. The spinning magnet was positioned so that its north and south poles passed by a piece of iron wrapped with insulated wire. Pixii found that the spinning magnet produced a pulse of current in the wire each time a pole passed the coil. However, the north and south poles of the magnet induced currents in opposite directions. To convert the alternating current to DC, Pixii invented a commutator, a split metal"

About 1856 he formulated the concept of the dynamo about six years before Siemens and Wheatstone but did not patent it as he thought he was not the first to realize this.

It was also the discovery of the principle of dynamo self-excitation, which replaced permanent magnet designs. The dynamo was the first electrical generator capable of delivering power for industry.
