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.. Wilde invented the dynamo-electric machine, or self-energising dynamo, an invention for which Werner von Siemens is more usually credited and, in … James Prescott Joule was an English physicist, mathematician, and inventor who established that the various forms of energy - mechanical, electrical, and heat - are basically the same and can be changed one into another. Rudolf Virchow was an eminent pathologist and politician, widely regarded as one of the greatest and most influential physicians in history. 61-82 1.
