James Wimshurst (April 13, 1832 – January 3, 1903) was a British inventor, engineer, and shipwright. Though Wimshurst did not patent his machines and the various improvements that he made to them, his refinements to the electrostatic generator led to its becoming widely known as the Wimshurst machine.

Biography
Wimshurst was born in Poplar, England and was the son of Henry Wimshurst. Wimshurst was educated at Steabonheath House in London, and then became an apprentice at the Thames ironworks until 1853 with James Mare. In 1864, he married Clare Tubb. In 1865, after Wimshurst was transferred to Liverpool, he worked at the Liverpool Underwriters' Registry. In 1874 he joined the Board of Trade, part of the Chamber of Commerce, as a "chief shipwright surveyor" at Lloyds. Later, in 1890, he would become the Board of Trade's representative at an international conference in Washington. The Board of Trade is a committee of the Privy Council of the United Kingdom, originating as a committee of inquiry in the 17th century and evolving gradually into a government department with a diverse range of functions. ...

Wimshurst dedicated large amounts of his free time to experimental works. Besides his electrical activities, Wimshurst would later invent a distinctive vacuum pump, a device to indicate ship stability, and methods for electrically connecting lighthouses to the mainland. In 1878 he began to experiment with electrical influence machines for generating electrical sparks for scientific and entertainment purposes. Beginning in 1880, Wimshurst became interested in electrostatic machines of the influence type. His house in Clapham, England had a versatile workshop, which possessed a wide variety of tools and devices for electric illumination. Wimshurst constructed several of the known types of electrostatic generators, such as those created by W. Nicholson, F. P. Carré and W. T. B. Holtz. To these predecessors, Wimshurst made many modifications with the result known as the Holtz-Wimshurst machine. A vacuum pump is a pump that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. ...

There have been several well-known people named William Nicholson, including: William Nicholson (artist) William Nicholson (chemist) William Nicholson (dramatist) William Nicholson (Mayor of Melbourne) Sir William Nicholson (soldier), British General, and Chief of the Imperial General Staff William Nicholson (naval officer) served in the United States Navy. ...
Shortly afterwards, Wimshurst developed a "duplex machine". The device had two disks turning in opposite directions, with metallic conducting sectors on the surfaces of each. Compared to its predecessors, this machine was less sensitive to atmospheric conditions and did not require an electric power supply. This form of the machine was also improved by other developers (such as the Pidgeon machine developed by W. R. Pidgeon, which increased the electrical induction effect and its electrical output). In 1882, Wimshurst developed his "Cylindrical Machine". By 1883, his improvements to the electrostatic generator led to the device being widely known as the Wimshurst machine. In 1885, one of the largest Wimshurst machines was built in England (and is now at the Chicago Museum of Science and Industry). 1882 (MDCCCLXXXII) was a common year starting on Sunday (see link for calendar). ...

Wimshurst became a member of the Institute of Electrical Engineers in 1889. In 1891, he reported a machine that generated high-tension alternating currents. In 1896, his multiple-disk machines (up to 8 disks) found a new use as Roentgen ray generators for radiography and electrotherapy. For this contribution to medical science, Wimshurst was elected a Fellow of the Royal Society (1898). He died in Clapham, England, at the age of 70.
