The Griffin Museum of Science and Industry (MSI), formerly known as the Museum of Science and Industry, is a science museum located in Chicago, Illinois, in Jackson Park, in the Hyde Park neighborhood between Lake Michigan and The University of Chicago. It is housed in the Palace of Fine Arts from the 1893 World's Columbian Exposition.
The Woolrich Electrical Generator of 1844, now in Thinktank, Birmingham Science Museum, is the earliest electrical generator used in an industrial process. [4] It was used by the firm of Elkingtons for commercial electroplating. [5] [6] [7]
During the 1950s he invented the insulating-core transformer, producing high-voltage direct current. He also developed tandem generator technology. The American Physical Society awarded him the T. Bonner prize (1965) for the development of electrostatic accelerators. Van de Graaff died on January 16, 1967, in Boston, Massachusetts. His wife ...
The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
Belgian engineer Zenobe Gramme who developed the DC generator accidentally discovered that a DC generator also works as a DC motor during an exhibit in Vienna. 1876: Paper capacitor manufacturing started. 1876: Russian engineer Pavel Yablochkov invented the electric carbon arc lamp. 1876: Scottish inventor Alexander Graham Bell patented the ...
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). Wimshurst became a member of the Institution of Electrical Engineers in 1889.

The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903).
