A 19th Century illustration of the Manchester Dynamo, an electrical generator that creates direct current using a commutator, the first electrical generators capable of delivering power for industry. Manchester based Henry Wilde (1833-1919) invented the dynamo-electric machine, or self-energising dynamo that replaced the permanent magnets of previous designs with electro-magnets and in so doing achieved an enormous increase in power. Werner von Siemens is more usually credited with the invention, but in fact, discovered independently.
