phonograph - thomas edison
Considered to be the first great Thomas Edison invention, and his life-long favorite, the phonograph would record the spoken voice and play it back. When speaking into the receiver, the sound vibration of the voice would cause a needle to create indentations on a drum wrapped with tin foil. Later Edison would adopt cylinders and discs to permanently record music. The first recorded message was of Thomas Edison speaking “Mary had a little lamb”, which greatly delighted and surprised Edison and -
light bulb - thomas edison
Thomas Edison is most well known for his invention of the light bulb. Contrary to popular belief, Edison did not invent the light bulb; it had been around for a number of years. The electric lights at the time, however, were unreliable, expensive, and short-lived. Over twenty distinct efforts by other inventors the world over were already underway when Edison entered the light bulb invention race. By creating a vacuum inside the bulb, finding the right filament to use, and running lower voltage -
Hermann Von Helmholtz
German physicist Hermann von Helmholtz gives a lecture in London in which he argues that electricity is divided into elementary particles similar to atoms. -
First Electric Railway
The first public electric railway, built by Siemens Halske near Berlin, opens. Seven years later the first electric trolley makes its debut in Virginia. In 1890, the first electric underground train begins service in London. -
electric iron - henry w seely
The electric iron was invented in 1882 by Henry W. Seeley, a New York inventor. Seeley patented his "electric flatiron" on June 6, 1882. His iron weighed almost 15 pounds and took a long time to warm up. Other electric irons had also been invented, including one from France (1882), but it used a carbon arc to heat the iron, a method which was dangerous. -
Heinrich Hertz
German physicist Heinrich Hertz proved the that electro magnetic waves travel over some distance. He was a German physicist who first conclusively proved the existence of electromagnetic waves theorized by James Clerk Maxwell's electromagnetic theory of light. -
J.J. Thomson
Electron discovered by J. J. Thomson. Thomson was the Cavendish professor of Experimental Physics at Cambridge University and director of its Cavendish Laboratory from 1884 until 1919.
