The Accreditation Board for Engineering and Technology (ABET), the primary accreditation organization for post-secondary engineering and technology departments in the United States, requires that all engineering curriculum include courses that teach students about the relationship between engineering practice and society. This paper first argues that many engineering schools are having difficulty meeting this requirement in a meaningful way. This paper then argues that history offers a wonderful stage on which to illustrate the engineering-society relationships. This paper then goes to present the results of the IEEE History Center's efforts to develop history of technology courses for engineering students

From a technical point of view, the international debate about the history of electrical transmission lines is widespread. Overhead lines and pylons, however, could be also analyzed in their cultural, aesthetic and natural meanings. In fact, they are symbols of modernity keeping the pace with the evolution of structures and technologies — since their origins until the present time. This essay is based on a comparative method, focusing on the international, historical context. At the same time, it was conceived as a multidisciplinary approach, linked to different themes: History of technology, Geography, Social and Political History, Literature and Arts.

The instruments used in the 20th Century to measure and set frequencies for the communications needs of land, sea and air forces are reviewed, with the aid of some examples of historic wavemeters used by British military units. The designs reflect the rapid advances in theory and practice of radio and electronics, stimulated particularly by World War 1, World War 2 and the Cold War, and illustrate how the methods and equipment used for frequency measurement changed dramatically, with progress from spark transmitters to microwave precision navigation systems.

Submarine cables developed quite early in a backwarded country like Italy after 1850. That was due mostly to the British standardized technology in the field. For some years Italy profited of its unique central position in the Mediterranean sea.

In the book by Robert Black: The History of Electric Wires and Cables. Peregrinus London 1983, 290 pages, the author Black deals with the individual screening of the three cores in a belted power cable, beginning on p. 109 and high-lightening on p. 111: “In the opinion of the writer this development, the introduction of the Hochstadter screen, was the most important single contribution to the art of cable making during the first quarter of the twentieth century.” Martin Höchstädter (1883–1973) — in original German spelling with two umlauts — left a type-written English manuscript of 7 pages, titled as in the headline and signed by him in 1967 when he was 84 years of age. Höchstädter's text is published here with comments by the editor, because after 50 years MH did not correctly remember the facts. A short biography is included with a portrait photo and an explanatory drawing of three-phase cable cross sections.

In capital of Russian empire, St.-Petersburg, on October, 21st, 1832 the Russian diplomat and outstanding scientist Baron Pavel L'vovitch Shilling in his big 5-rooms apartment in the house on Tsaritsyn meadow (now Marsovo pole, 7), has arranged the public demonstration of the first electromagnetic telegraph invented by him. So in Russia there was first-ever suitable to practical use an electromagnetic telegraph. This day now is considered as birthday of Russian telecommunication. In this paper we briefly present the biography of Pavel Shilling, describe how the first electromagnetic telegraph has been invented. We also present academician B. S. Jakobi (1801–1874) who continued works of Shilling and created more perfective electromagnetic telegraphs. Finally this paper shows the evolution of telegraph to the modern communication in Russia.

The world's first commercial facsimile service began between Paris and Lyon in 1865, reflecting a conjunction of good design, superb craftsmanship, need for a faster alternative to Morse telegraphy, and imperial patronage. Although technological and economic shortcomings stopped Abbe Caselli's pantelegraphs in 1867, the French telegraph administration tested other fax systems to increase the speed and accuracy of telegram service. Facsimile machines proved faster than conventional Morse machines, but the automatic printing telegraph was even faster and less expensive. Other countries faced similar challenges with telegraphy, but patronage and craftsmanship distinguished facsimile in France.

Liquid-crystal display (LCD) was invented in 1964 at RCA Laboratories in Princeton, NJ. In 1970, twisted-nematic (TN) mode of operation was discovered, which gave LCD the first commercial success. The LCD manufacturers supplied small-size displays to portable products such as digital watches and pocket calculators. In 1988, Sharp Corporation demonstrated a 14-in. active-matrix full-color full-motion display using a TFT (thin-film-transistor) array. Observing this, Japan launched a true LCD industry. Large-size displays were first supplied to personal computers and then to television receivers. In the second half of 1990s, the industry has moved to Korea and Taiwan.
