	Inventor Heinrich Hertz
		Heinrich Rudolf Hertz, German physicist, born in Hamburg, and educated at the University of Berlin.
		Hertz proved that electricity can be transmitted in electromagnetic waves, which travel at the speed of light and which possess many other properties of light.
		Before Hertz gained professorships in Karlsruhe and Bonn, he had studied under the famous scientist Hermann von Helmholtz in Bonn, and it was Helmholtz who encouraged Hertz to attempt to win the science prize that led to some of Hertz's most important discoveries.

		Carl Hellmuth Hertz, the son of Nobel Laureate Gustav Hertz, was working as a graduate student in nuclear physics at the time.
		Hertz's father had been the director of the Siemens research laboratory before the end of the war, and Edler and Carl Hertz were able to contact Wolfgang Gellinek, director of the Siemens medical branch in Erlangen, Germany, to borrow one of the Siemens ultrasound reflectoscopes in October 1953.
		Edler and Hertz validated their observations with an in vitro animal model, demonstrating the planes of the echo beam and the structures that would reflect signals.

		Medical ultrasonography was invented in 1953 at Lund University by cardiologist Inge Edler and Carl Hellmuth Hertz, the son of Gustav Ludwig Hertz, who was a graduate student at the department for nuclear physics.
		On December 16 the same year, the method was used to generate an echo-encephalogram (ultrasonic probe of the brain).

		It was of course well known, as a necessity of Maxwell's mathematical theory, that the polarization and depolarization of an insulator must give rise to the same electromagnetic effects in the neighborhood as a voltaic current in a conductor.
		Hertz himself gave an admirable account of the significance of his discoveries in a lecture on the relations between light and electricity, delivered before the German Society for the Advancement of Natural Science and Medicine at Heidelberg in September 1889.
		In 1889 Hertz was appointed to succeed R. Clausius as ordinary professor of physics in the University of Bonn.

	History of Ultrasound in Obstetrics and Gynecology, part 1
		The availability of very high input impedance amplifiers built from improved quality electrometer tubes in the early 1950s enabled engineers to greatly amplify their signals to improve sensitivity and stability in their commercial equipments.
		These reflectoscopes became the precursors of subsequent pulse-echo medical ultrasonic devices operating in the uni-directional A-mode and had been used as early as 1950 by Lars Leksell in Sweden and JC Turner in London for examining brain lesions and Inge Edler and Carl Hellmuth Hertz in producing their first cardiac M-mode tracings in 1953.
		The Japanese were also active at investigating and producing similar ultrasonic devices but their findings have only been sparsely documented in the English literature.
