11 Marrison, Warren Alvin
[br]b. 21 May 1896 Inverary, Canadad. 27 March 1980 Palo Verdes Estates, California, USA[br]Canadian (naturalized American) electrical engineer, pioneer of the quartz clock.[br]Marrison received his high-school education at Kingston Collegiate Institute, Ontario, and in 1914 he entered Queen's University in Kingston. He graduated in Engineering Physics in 1920, his college career having been interrupted by war service in the Royal Flying Corps. During his service in the Flying Corps he worked on radio, and when he returned to Kingston he established his own transmitter. This interest in radio was later to influence his professional life.In 1921 he entered Harvard University, where he obtained an MA, and shortly afterwards he joined the Western Electric Company in New York to work on the recording of sound on film. In 1925 he transferred to Western Electric's Bell Laboratory, where he began what was to become his life's work: the development of frequency standards for radio transmission. In 1922 Cady had used the elastic vibration of a quartz crystal to control the frequency of a valve oscillator, but at that time there was no way of counting and displaying the number of vibrations as the frequency was too high. In 1927 Marrison succeeded in dividing the frequency electronically until it was low enough to drive a synchronous motor. Although his purpose was to determine the frequency accurately by counting the number of vibrations that occurred in a given time, he had incidentally produced the first quartz-crystal -ontrolled clock. The results were sufficiently encouraging for him to build an improved version the following year, specifically as a time and frequency standard.[br]Principal Honours and DistinctionsBritish Horological Institute Gold Medal 1947.

14 Hertz, Heinrich Rudolph
[br]b. 22 February 1857 Hamburg, Germanyd. 1 January 1894 Bonn, Germany[br]German physicist who was reputedly the first person to transmit and receive radio waves.[br]At the age of 17 Hertz entered the Gelehrtenschule of the Johaneums in Hamburg, but he left the following year to obtain practical experience for a year with a firm of engineers in Frankfurt am Main. He then spent six months at the Dresden Technical High School, followed by year of military service in Berlin. At this point he decided to switch from engineering to physics, and after a year in Munich he studied physics under Helmholtz at the University of Berlin, gaining his PhD with high honours in 1880. From 1883 to 1885 he was a privat-dozent at Kiel, during which time he studied the electromagnetic theory of James Clerk Maxwell. In 1885 he succeeded to the Chair in Physics at Karlsruhe Technical High School. There, in 1887, he constructed a rudimentary transmitter consisting of two 30 cm (12 in.) rods with metal balls separated by a 7.5 mm (0.3 in.) gap at the inner ends and metallic plates at the outer ends, the whole assembly being mounted at the focus of a large parabolic metal mirror and the two rods being connected to an induction coil. At the other side of his laboratory he placed a 70 cm (27½ in.) diameter wire loop with a similar air gap at the focus of a second metal mirror. When the induction coil was made to create a spark across the transmitter air gap, he found that a spark also occurred at the "receiver". By a series of experiments he was not only able to show that the invisible waves travelled in straight lines and were reflected by the parabolic mirrors, but also that the vibrations could be refracted like visible light and had a similar wavelength. By this first transmission and reception of radio waves he thus confirmed the theoretical predictions made by Maxwell some twenty years earlier. It was probably in his experiments with this apparatus in 1887 that Hertz also observed that the voltage at which a spark was able to jump a gap was significantly reduced by the presence of ultraviolet light. This so-called photoelectric effect was subsequently placed on a theoretical basis by Albert Einstein in 1905. In 1889 he became Professor of Physics at the University of Bonn, where he continued to investigate the nature of electric discharges in gases at low pressure until his death after a long and painful illness. In recognition of his measurement of radio and other waves, the international unit of frequency of an oscillatory wave, the cycle per second, is now universally known as the Hertz.[br]Principal Honours and DistinctionsRoyal Society Rumford Medal 1890.BibliographyMuch of Hertz's work, including his 1890 paper "On the fundamental equations of electrodynamics for bodies at rest", is recorded in three collections of his papers which are available in English translations by D.E.Jones et al., namely Electric Waves (1893), Miscellaneous Papers (1896) and Principles of Mechanics (1899).Further ReadingJ.G.O'Hara and W.Pricha, 1987, Hertz and the Maxwellians, London: Peter Peregrinus.
