21 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.

23 INTRODUCTION
For a small country perched on the edge of western Europe but with an early history that began more than 2,000 years ago, there is a vast bibliography extant in many languages. Since general reference works with bibliography on Portugal are few, both principal and minor works are included. In the first edition, works in English, and a variety of Portuguese language works that are counted as significant if not always classic, were included. In the second and third editions, more works in Portuguese are added.It is appropriate that most of the works cited in some sections of the bibliograpy are in English, but this pattern should be put in historical perspective. Since the late 1950s, the larger proportion of foreign-language works on Portugal and the Portuguese have been in English. But this was not the case before World War II. As a whole, there were more studies in French, with a smaller number in German, Italian, and Spanish, than in English. Most of the materials published today on all aspects of this topic continue to be in Portuguese, but English-language works have come to outnumber the other non-Portuguese language studies. In addition to books useful to a variety of students, a selection of classic works of use to the visitor, tourist, and foreign resident of Portugal, as well as to those interested in Portuguese communities overseas, have been included.Readers will note that publishers' names are omitted from some Portuguese citations as well as from a number of French works. There are several reasons for this. First, in many of the older sources, publishers no longer exist and are difficult to trace. Second, the names of the publishers have been changed in some cases and are also difficult to trace. Third, in many older books and periodicals, printers' names but not publishers were cited, and identifying the publishers is virtually impossible.Some recommended classic titles for beginners are in historical studies: José Hermano Saraiva, Portugal: A Companion History (1997); A. H. de Oliveira Marques, History of Portugal (1976 ed.), general country studies in two different historical eras: Sarah Bradford, Portugal (1973) and Marion Kaplan, The Portuguese: The Land and Its People (2002 and later editions); political histories, Antônio de Figueiredo, Portugal: Fifty Years of Dictatorship (1975) and Douglas L. Wheeler, Republican Portugal: A Political History ( 1910-1926) (1978; 1998). On Portugal's Revolution of 25 April 1974 and contemporary history and politics: Kenneth Maxwell, The Making of Portuguese Democracy (1995); Phil Mailer, The Impossible Revolution (1977); Richard A. H. Robinson, Contemporary Portugal: A History (1979); Lawrence S. Graham and Douglas L. Wheeler (eds.), In Search of Modern Portugal: The Revolution and Its Consequences (1983); Lawrence S. Graham and Harry M. Makler (eds.), Contemporary Portugal: The Revolution and its Antecedents (1979). On contemporary Portuguese society, see Antonio Costa Pinto (ed.), Contemporary Portugal: Politics, Society, Culture (2003).Enduring works on the history of Portugal's overseas empire include: C. R. Boxer, The Portuguese Seaborne Empire, 1415-1825 (1969 and later editions); and Bailey W. Diffie and George Winius, The Foundations of the Portuguese Empire, 1415-1580 (1977); on Portugal and the Age of Discoveries: Charles Ley (ed.), Portuguese Voyages 1498-1663 (2003). For a new portrait of the country's most celebrated figure of the Age of Discoveries, see Peter Russell, Prince Henry 'The Navigator': A Life (2000). A still useful geographical study about a popular tourist region is Dan Stanislawski's Portugal's Other Kingdom: The Algarve (1963). A fine introduction to a region of rural southern Portugal is José Cutileiro's A Portuguese Rural Society (1971).Early travel account classics are Almeida Garrett, Travels in My Homeland (1987) and William Beckford, Recollections of an Excursion to the Monasteries of Alcobaca and Batalha (1969 and later editions). On travel and living in Portugal, see Susan Lowndes Marques and Ann Bridge, The Selective Traveller in Portugal (1968 and later editions); David Wright and Patrick Swift, Lisbon: A Portrait and Guide (1968 and later editions); Sam Ballard and Jane Ballard, Pousadas of Portugal (1986); Richard Hewitt, A Cottage in Portugal (1996);Ian Robertson, Portugal: The Blue Guide (1988 and later editions); and Anne de Stoop, Living in Portugal (1995). Fine reads on some colorful, foreign travellers in Portugal are found in Rose Macauley, They Went to Portugal (1946 and later editions) and They Went to Portugal Too (1990). An attractive blend of historical musing and current Portugal is found in Paul Hyland's, Backing Out of the Big World: Voyage to Portugal (1996); Datus Proper's The Last Old Place: A Search through Portugal (1992); and Portugal's 1998 Nobel Prize winner in Literature, José Sarmago, writes in Journey through Portugal (2001).For aspects of Portuguese literature in translation, see Aubrey F. G. Bell, The Oxford Book of Portuguese Verse (1952 edition by B. Vidigal); José Maria Eça de Queirós, The Maias (2007 and earlier editions); and José Sara-mago's Baltasar and Blimunda (1985 and later editions), as well as many other novels by this, Portugal's most celebrated living novelist. See also Landeg White's recent translation of the national 16th century epic of Luis de Camóes, The Lusiads (1997). A classic portrait of the arts in Portugal during the country's imperial age is Robert C. Smith's The Art of Portugal, 1500-1800 (1968).For those who plan to conduct research in Portugal, the premier collection of printed books, periodicals, and manuscripts is housed in the country's national library, the Biblioteca Nacional de Lisboa, in Lisbon. Other important collections are found in the libraries of the major universities in Coimbra, Lisbon, and Oporto, and in a number of foundations and societies. For the history of the former colonial empire, the best collection of printed materials remains in the library of Lisbon's historic Geography Society, the Sociedade de Geografia de Lisboa, Lisbon; and for documents there is the state-run colonial archives, the Arquivo Historico Ultramarino, in Restelo, near Lisbon. Other government records are deposited in official archives, such as those for foreign relations in the archives of the Ministry of Foreign Affairs, housed in Necessidades Palace, Lisbon.For researchers in North America, the best collections of printed materials on Portugal are housed in the Library of Congress, Washington, D.C.; New York Public Library, New York City; Newberry Library, Chicago, Illinois; and in university libraries including those of Harvard, Yale, Johns Hopkins, Brown, Indiana, Illinois, University of California at Los Angeles, University of California - Berkeley, University of California - Santa Barbara, Stanford, Florida State, Duke, University of New Hampshire, Durham, University of Toronto, University of Ottawa, McGill, and University of British Columbia. Records dealing with Portuguese affairs are found in U.S. government archives, including, for instance, those in the National Archives and Record Service (NARS), housed in Washington, D.C.BIBLIOGRAPHIES■ Academia Portuguesa de História.

24 Fessenden, Reginald Aubrey
[br]b. 6 October 1866 East Bolton, Quebec, Canadad. 22 July 1932 Bermuda[br]Canadian radio pioneer who made the first known broadcast of speech and music.[br]After initial education at Trinity College School, Port Hope, Ontario, Fessenden studied at Bishops University, Lennoxville, Quebec. When he graduated in 1885, he became Principal of the Whitney Institute in Bermuda, but he left the following year to go to New York in pursuit of his scientific interests. There he met Edison and eventually became Chief Chemist at the latter's Laboratory in Orange, New Jersey. In 1890 he moved to the Westinghouse Electric and Manufacturing Company, and two years later he returned to an academic career as Professor of Electrical Engineering, initially at Purdue University, Lafayette, Indiana, and then at the Western University of Pennsylvania, where he worked on wireless communication. From 1900 to 1902 he carried out experiments in wireless telegraphy at the US Weather Bureau, filing several patents relating to wire and liquid thermal detectors, or barretters. Following this he set up the National Electric Signalling Company; under his direction, Alexanderson and other engineers at the General Electric Company developed a high-frequency alternator that enabled him to build the first radiotelephony transmitter at Brant Rock, Massachusetts. This made its initial broadcast of speech and music on 24 December 1906, received by ship's wireless operators several hundred miles away. Soon after this the transmitter was successfully used for two-way wireless telegraphy communication with Scotland. Following this landmark event, Fessenden produced numerous inventions, including a radio compass, an acoustic depth-finder and several submarine signalling devices, a turboelectric drive for battleships and, notably, in 1912 the heterodyne principle used in radio receivers to convert signals to a lower (intermediate) frequency.[br]Principal Honours and DistinctionsInstitute of Electrical and Electronics Engineers Medal of Honour 1921.BibliographyUS patents relating to barretters include nos. 706,740, 706,742 and 706,744 (wire, 1902) and 731,029 (liquid, 1903). His invention of the heterodyne was filed as US patent no. 1,050,441 (1913).Further ReadingHelen M.Fessenden, 1940, Fessenden. Builder of Tomorrow.
