  • German-British Rivalry and Visions of Global Communications in the Early Twentieth Century
    How Not to Build a World Wireless Network: German-British Rivalry and Visions of Global Communications in the Early Twentieth Century Heidi Tworek Assistant Professor of International History University of British Columbia 1873 East Mall, Room 1297 Vancouver, BC V6T 1Z1 Canada This is a preprint version of an article that appears in History and Technology: An International Journal 32, no. 2 (2016): 178-200. The journal is published by Taylor & Francis. The article DOI is: 10.1080/07341512.2016.1217599 The published version can be found here. Abstract: Edward Snowden’s revelations laid bare an unprecedented scale of state influence on communications technology. But government elites have frequently shaped technological development through their beliefs about potentially nefarious uses of communications. This article argues that beliefs about how other states or groups might use a technology can shape innovation. In particular, German visions about the British use of cables spurred German investment in developing wireless telegraphy. Germans imagined that the British were using cable technology to damage Germany’s reputation, spy on Germany and ‘poison’ neutral countries against the Central Powers. The German government and military at first created a colonial wireless network to bypass British cables. In World War I, however, they sought to establish a world wireless network. In the end, innovation was significantly shaped by how Germans imagined their enemies’ uses of communications technology. Keywords: wireless, radio, Germany, World War I, Britain, colonialism, imperialism 1 Sophus Larsen was in trouble. He needed money, and fast. In November 1917, his company, Larsen & Co., had signed a contract with the Chinese government to erect three wireless stations on Chinese soil.

  • ELECTRICITY AS the MEDIUM of PSYCHIC LIFE Argument "Here in Front of My Eyes, in the Graph with All Its Peaks and Numbers
    ELECTRICITY AS THE MEDIUM OF PSYCHIC LIFE PSYCHOTECHNICS, THE RADIO, AND THE ELECTROENCEPHALOGRAM IN WEIMAR GERMANY Cornelius Borck Argument The commodification of electricity since 1900 furnished the 'civilized' world with new attractions and revolutionized everyday-life with all forms of tools and gadgets; it also opened up – technically and intellectually – a new space for investigating psycho-physical interaction, reviving ideas of a close linkage between psychic life and electricity. The paper traces the emergence of this electro-psychological framework beyond 'electroencephalography,' the recording of electrical brain waves, to 'diagnoscopy,' a personality profiling by an electric phrenology. Diagnoscopy opens up a window on to the scientific and public cultures of electricity and psychical processes in Weimar Germany. It garnered enormous attention in the press and was quickly taken up by several institutions for vocational guidance, because it offered a rapid and technological alternative to laborious psychological testing or 'subjective' interviewing. Academic psychology and leading figures in brain research reacted with horror; forging counter measures which finally resulted in this technique being denounced as quackery. A few years later, the press celebrated electroencephalography as a mind reading device, whereas Berger's colleagues remained skeptical of its significance and the very possibility of an 'electroencephalogram,' before they adapted electroencephalography as a tool for representing various neuro-psychiatric conditions in patterns of recorded signals. The blending of holistic psychophysiology and electrical engineering marks the formation of an electric epistemology in the scientific as well as public understanding of the psyche. The transformations of electrodiagnosis, from Bissky and popular electric psychophysiology to Berger, are indicative of a larger cultural shift in which electricity changed its role from being the power source for experimental apparatuses to becoming the medium of psychic processes.

  • Guglielmo MARCONI (25 April 1874-20 July 1937)
    1 Guglielmo MARCONI (25 April 1874-20 July 1937) PART 1: HIS LIFE AND COMPANY Introduction Wireless telegraphy was the outcome of a chain of effort formed by the mathematician, the laboratory experimenter, the inventor, and the capitalist. For instance: in 1864, James Clerk Maxwell (1831-1879) working on purely theoretical lines, reached the conclusion that an electric spark or disruptive discharge," would set up oscillations in the ether”. In 1887, Heinrich Hertz (1857-1894) proved by experiments that Clerk Maxwell's theory was correct. He demonstrated that an electric spark “brings about the radiation of etheric waves” which may be reflected, refracted, and polarised like those of light. In 1895, Guglielmo Marconi began his attempts to utilise these waves for signalling purposes. In 1896, he took out the first of the patents which were later acquired by Marconi's Wireless Telegraph Company, and utilised in the development of a world-wide system of wireless telegraphy by land and sea. 1. THE EARLY YEARS (a),[3] 1.1. Guglielmo Marconi’s youth On April 25, 1874, an event occurred which would change the world forever: on that day Guglielmo Marconi was born in Bologna, Italy. His first influences proved unusual: His father, Giuseppe, was an able, dignified Catholic Italian businessman. His mother, Annie a Protestant Irish girl of Daphne Castle, County Wexford, was descended from a family of well-known Jameson whiskey distillers in Dublin. Their first child, Alfonso, had been born nine years before Guglielmo. Neat, tidy, studious and obedient, he was nearly the opposite of his younger brother.

As a media archaeology of wirelessness, this dissertation situates the “discovery” of electromagnetic radiation and the “invention” of wireless transmission in a richer field of scientific, experimental, and aesthetic relations during the early and pre-history of national broadcasting. Before wireless transmission came to be synonymous with the mass distribution medium of radio or even the long-distance communication medium of wireless telegraphy, it was at the center of speculation about a variety of possible wireless

  • The Beginnings of Radio Communication in Germany, 1897-1918
    Journal of Radio Studies/Volume 7, No. 2, 2000 The Beginnings of Radio Communication in Germany, 1897-1918 Michael Friedewald Fraunhofer Institute for Systems and Innovation Research, Karlsruhe, Germany This article surveys the prehistory of broadcasting in the German Reich. It focuses on wireless telegraphy, where the Telefunken Company succeeded internationally with its quenched spark system on the eve of the war. Telefunken's system was developed as an efficient military technology between 1905 and 1908, and it soon became the core of Telefunken's successful attempt to break Marconi's monopoly in maritime radio communication. Encouraged by this success, Telefunken started to establish wireless transoceanic connections to build a global German radio network. The properties of radio broadcasting as a possible new mass medium only gradually became evident before 1918. There is hardly a technology that shaped the face of the 20th century more than the electrical communications technology and the mass media. Radio and television, telephone and fax machines are a part of the everyday life of billions of people. But before the radio age began around 1920, wireless communications technology was already 25 years old. In Germany—as in other countries—this time was a phase of a multitude of competing systems for wireless telegraphy. No less than four different technologies were widely used: spark transmitters, arc transmitters, high frequency alternators, and finally vacuum-tube transmitters. This diversity of technologies resulted from an intensive search for ways to generate electromagnetic waves. However, during the first years, radio communication stood in direct competition to submarine cables, a technology that had by 1900 been brought to a high degree of technical efficiency.

  • 2 Hans Berger's Long Path to The
    Brainwaves In the history of brain research, the prospect of visualizing brain processes has continually awakened great expectations. In this study, Cornelius Borck focuses on a recording technique developed by the German physiologist Hans Berger to register electric brain currents; a technique that was expected to allow the brain to write in its own language, and which would reveal the way the brain worked. Borck traces the numerous contradictory interpretations of electroencephalography, from Berger’s experiments and his publication of the first human EEG in 1929, to its international proliferation and consolidation as a clinical diagnostic method in the mid-twentieth century. Borck’s thesis is that the language of the brain takes on specific contours depending on the local investigative cultures, from whose conflicting views emerged a new scientific object: the electric brain. Cornelius Borck is Professor of History, Theory and Ethics of Medicine and Science and Director of the Institute of History of Medicine and Science Studies at the University of Lübeck, Germany.
