Göttingen Seven The Göttingen Seven (German: "Göttinger Sieben" ) were a group of seven professors from Göttingen. In 1837, they protested against the abolition or alteration of the constitution of the Kingdom of Hanover by Ernest Augustus and refused to swear an oath to the new king of Hanover. The company of seven was led by Friedrich Christoph Dahlmann, who himself was one of the key advocates of the unadulterated constitution. The other six were the Germanist brothers Wilhelm and Jacob Grimm (famed fairy tale and folk tale writers and storytellers, known together as the Brothers Grimm), jurist Wilhelm Eduard Albrecht, historian Georg Gottfried Gervinus, physicist Wilhelm Eduard Weber, and theologian and orientalist Heinrich Georg August Ewald.

Bolometer A bolometer is a device for measuring the power of incident electromagnetic radiation via the heating of a material with a temperature-dependent electrical resistance. It was invented in 1878 by the American astronomer Samuel Pierpont Langley.

Marconi's law Marconi's law is the relation between height of antennas and maximum signaling distance of radio transmissions. Guglielmo Marconi enunciated at one time an empirical law that, for simple vertical sending and receiving antennas of equal height, the maximum working telegraphic distance varied as the square of the height of the antenna. It has been stated that the rule was tested in experiments made on Salisbury Plain in 1897, and also by experiments made by Italian naval officers on behalf of the Royal Italian Navy in 1900 and 1901. Captain Quintino Bonomo gave a report of these experiments in an official report.

Julius Wilhelm Gintl Julius Wilhelm Gintl was an Austrian physicist. He was notable as the developer of an early form of duplex electrical telegraph, which allowed two messages to be transmitted on a single wire, in opposite directions. This "duplex" communication was an early specific case of the general practice of multiplexing.

Tesla's Egg of Columbus Nikola Tesla, at the 1893 World's Columbian Exposition, demonstrated a device he constructed known as the "Egg of Columbus." It was used to demonstrate and explain the principles of the rotating magnetic field model and the induction motor. It was also used to rotate armatures at great distances and speeds in the first demonstration of wireless power transfer.

Oliver Lodge Sir Oliver Joseph Lodge, {'1': ", '2': ", '3': ", '4': "} (12 June 1851 – 22 August 1940) was a British physicist and writer involved in the development of, and holder of key patents for, radio. He identified electromagnetic radiation independent of Hertz' proof and at his 1894 Royal Institution lectures (""The Work of Hertz and Some of His Successors""), Lodge demonstrated an early radio wave detector he named the "coherer". In 1898 he was awarded the "syntonic" (or tuning) patent by the United States Patent Office. Lodge was Principal of the University of Birmingham from 1900 to 1920.

Technische Universität Darmstadt The Technische Universität Darmstadt (unofficially Technical University of Darmstadt or Darmstadt University of Technology), commonly referred to as TU Darmstadt, is a research university in the city of Darmstadt, Germany. It was founded in 1877 and received the right to award doctorates in 1899. In 1882 it was the first university in the world to set up a chair in electrical engineering, and founded the first faculty for it in 1883.

Heinrich Welker Heinrich Johann Welker (September 9, 1912 in Ingolstadt – December 25, 1981 in Erlangen) was a German theoretical and applied physicist who invented the "transistron", a transistor made at Westinghouse independently of the first successful transistor made at Bell Laboratories. He did fundamental work in III-V compound semiconductors, and paved the way for microwave semiconductor elements and laser diodes.
