History of siemens

Siemens was founded by Werner von Siemens on 1 October 1847. Based on the telegraph, his invention used a needle to point to the sequence of letters, instead of using Morse code. The company – then called Telegraphen-Bauanstalt von Siemens & Halske – opened its first workshop on October 12. In 1848, the company built the first long-distance telegraph line in Europe; 500 km from Berlin to Frankfurt am Main. In 1850 the founder's younger brother, Sir William Siemens (born Carl Wilhelm Siemens), started to represent the company in London. In the 1850s, the company was involved in building long distance telegraph networks in Russia. In 1855, a company branch headed by another brother, Carl von Siemens, opened in St Petersburg, Russia. In 1867, Siemens completed the monumental Indo-European (Calcutta to London) telegraph line.[4] In 1881, a Siemens AC Alternator driven by a watermill was used to power the world's first electric street lighting in the town of Godalming, United Kingdom. The company continued to grow and diversified into electric trains and light bulbs. In 1890, the founder retired and left the company to his brother Carl and sons Arnold and Wilhelm. Siemens & Halske (S&H) was incorporated in 1897. In 1919, S&H and two other companies jointly formed the Osram lightbulb company. A Japanese subsidiary was established in 1923. During the 1920s and 1930s, S&H started to manufacture radios, television sets, and electron microscopes.
