Although the start of the synthetic detergent industry is not shrouded in the veils of history as were the beginnings of the soap industry, it is nevertheless not easy to pinpoint exactly when the detergent industry, as such, came into being. The primary problem is to decide exactly what is being referred to as a synthetic detergent. The term itself leads to confusion. In the USA the words surfactant or syndet are being used, whilst in Europe the term 'tenside' (for tensio-active material) is coming into fashion.

This is the name of the journal which contains papers presented at the annual meetings of Dyes in History and Archaeology, formerly known as the Association of Researchers into Dyes in History and Archaeology

I størst oplag kom dog den klassiske tier, der ligesom plovmanden skiftede tekst fra den viste til "Nationalbankens sedler indløses med guld efter gældende lov" i 1930. Nederst vises Heilmanns første udkast til tieren. Der er sket væsentlige ændringer mellem det og det endelige resultat.

These links contain the exhibits pages with information on various patents, caveats, and telegraph development. Rules for the simulation can be found in Exhibit 4.

The Mercurians began meeting in 1986 for the purpose of generating networks between people who share work and interests in the history of communication technologies, defining the field broadly. Our activities include publishing a semi-annual newsletter, Antenna, meeting annually at Society for the History of Technology (SHOT) conferences, organizing paper sessions for SHOT meetings, and pursuing contacts between meetings. Antenna serves both as a clearing house for readers and an informal forum for their ideas. We welcome contributions, including notices and queries about Mercurians' projects as well as short essays on their work. Antenna includes book reviews and other materials about conferences, museums, publications, archives, funding, and other pertinent materials.

Few today are aware of the role that telegraphers played in providing global communications and operating the railroad system in the nineteenth and early twentieth centuries. These "wizards of the wire" enabled ordinary small-town people to receive news and personal messages from afar; they prevented railroad collisions and enabled trains to run on time.

For those who remember the work of the telegraph operators, the image that comes to mind is generally that of a male, since women, according to a still-common misconception, "didn't do that kind of work." Yet in 1897, B. B. Adams, editor of Railroad Gazette, could state that at railroad stations "where the business has increased enough to warrant the employment of an assistant, a young woman to do the telegraphing is frequently the first helper employed." This website provides research resources for telegraphy and women's participation in this early technical occupation, and also provides links to related sites.

Elisha Gray (born in Barnesville, Ohio, on Aug. 2, 1835, died Newtonville, Mass., on Jan. 21, 1901) would have been known to us as the inventor of the telephone if Alexander Graham bell hadn't got to the patent office one hour before him. Instead, he goes down in history as the accidental creator of one of the first electronic musical instruments - a chance by-product of his telephone technology.
