34 Panorama GREAT INVENTORS The Siemens & Halske cable plant in St. Petersburg, Russia. Built in 1882 replacement. In 1845 at a meeting of the Berlin Physics Society, which attracted everyone who was keen on modern technology, Siemens described his idea of a synchronous switch telegraph. One of the members of the audience was Berlin’s best mechanic Johann Georg Halske, who told the presenter that he would be able to improve the design and start a small batch production of the machine. Subsequent events followed in a frenzy of action. Siemens and Halske, leaving aside all other business, quickly assembled a prototype and were able to persuade their military supervisors that the device would be able to provide the Prussian army with a quick and reliable means of communications. Several months later Siemens was invited Dynamo apparatus designed by Werner Siemens Johann Georg Halske Switch telegraph designed by Werner Siemens

On December 14, 1846, the day following his 30th birthday, Siemens wrote to a relative: “I have almost decided to pursue a career in telegraphy irrespective of whether it can be combined with my military service. In time telegraphy will become a separate important part of technology, and I see my calling in becoming the organizing force of this.” Within a period of ten months Siemens and Halske received several lucrative orders and on October 1, 1847 they founded the Telegraphenbauanstalt Siemens & Halske company. In 1849 Werner Siemens retired from military service and focused on his inventions. During the same year Siemens & Halske built Europe’s first electric telegraph line between Berlin and Frankfurt. After their initial success the company was flooded with orders, and even some imperfections in the early projects, caused by the authorities’ reluctance to provide Siemens & Halske with adequate funding required for procuring high-quality materials, could not prevent it from flourishing. Also, very soon the company received significant assistance from overseas. One of Werner’s younger brothers, Karl, unexpectedly secured a contract in Russia to build a telegraph line between St. Petersburg and Moscow. The job was finished in 1851 and became the first for Siemens in the huge Russian market. During the Crimean War on the Black Sea communications lines were installed to Sevastopol, allowing telegraph connections for large cities like Kiev and Odessa. New contracts from the Russian Empire continued to arrive over the next 50 years, and Russia became a key partner for Siemens & Halske. Russian authorities again contracted the company when it was required to lay a cable under water, across the Baltic Sea, another first in human history. Several years later the Siemenses did Russia a favor by persuading European countries to install the line between London and Calcutta via the Russian Caucasus, bypassing Turkey. Building telegraph lines was the main specialization, but not the only one for Siemens & Halske. Siemens himself, an explorer by nature, would be reluctant to focus on just one thing. After handing the telegraph business to his commercially savvy brothers he started designing other things. Just before he turned 50 years old Siemens began work on the design of a device that would generate current without relying on batteries, a dynamo machine. This produced the direct current generator which spurred on a revolution in various spheres of human life. The Siemens dynamo machine allowed miners to utilize power tools, electric cars and electric trains for transporting ore. Most importantly, the dynamo machine made it possible to develop electric transportation in general. Already in 1879 at the World Trade Fair Siemens demonstrated his electric railroad, which carried visitors between pavilions. Two years later his company built the first electric streetcar line in a Berlin suburb. Over time construction of electric Map of telegraph lines built by Siemens & Halske in the Russian Empire
