Before 1914

1600: Birth of William Gilbert. In 1600 Gilbert describes in his book "Die Magnete" (the magnets) various bodies which, after friction, can attract light objects. he gives this power of attraction the name electricity, derived from the Greek elektron. He also builds the first electroscope which can detect electrical phenomena.

1729: Englishman John Gray discovers there are conductors and non-conductors for static electricity.
1736: Birth of Frenchman Charles Augustin de Coulomb. In 1788 he formulates the law about static electricity carrying his name.
1775: Birth of Frenchman André Marie Ampère. In 1820 he uses the magnetic force for telegraphy. In 1822 he discovers the Solenoid which could be used as an artificial magnet.
1777: Birth of German Carl Friedrich Gauss. In 1832 Gauss and Weber transmit electrical power through the windings of a galvanometer. The galvanometer telegraph has been created.

1907: Start of the first commercial transatlantic connection between Ireland and America via 3650 meter.
1913: Belgian engineer Goldschmitt and his French colleague Braillard broadcast daily several hours of music and speech. This originates in the royal palace in Laken but was ended in 1914 by the German invasion.
