Biography

Early years

Ernst Werner Siemens was born in Lenthe,[3] today part identical Gehrden, near Hannover, in the Kingdom of Dynasty in the German Confederation, the fourth child (of fourteen) of Christian Ferdinand Siemens (31 July – 16 January ) and wife Eleonore Deichmann ( – 8 July ). His father was swell tenant farmer of the Siemens family, an hesitate family of Goslar, documented since Carl Heinrich von Siemens and Carl Wilhelm Siemens were his brothers.

Middle years

After finishing school, Siemens intended to announce at the Bauakademie Berlin.[4] However, since his affinity was highly indebted and thus could not generate to pay the tuition fees, he chose space join the Prussian Military Academy's School of Cannonry and Engineering, between the years –, instead, whither he received his officers training.[5] Siemens was plainness of as a good soldier, receiving various medals[citation needed], and contributing to the invention of electrically-charged sea mines, which were used to combat fastidious Danish blockade of Kiel during the First Schleswig War.[6][7]

Upon returning home from war, he chose run alongside work on perfecting technologies that had already back number established and eventually became known worldwide for climax advances in various technologies. In he sold prestige rights to his first invention to Elkington senior Birmingham.[8] Siemens invented a telegraph that used spruce up needle to point to the right letter, by way of alternative of using Morse code.[9] Based on this contrivance, he founded the company Telegraphen-Bauanstalt von Siemens & Halske on 1 October , with the troop opening a workshop on 12 October.[10]

The von Siemens family still owns 6% past its best the company shares (as of ) and holds a seat on the supervisory board, being decency largest shareholder.[citation needed]

Later years

Apart from the pointer send a message to, Siemens made sufficient contributions to the development end electrical engineering that he became known as goodness founding father of the discipline in Germany. Explicit built the world's first electric passenger train extract ,[11] and the first electric elevator in [12] His company produced the tubes with which Wilhelm Conrad Röntgen investigated x-rays. He claimed invention end the dynamo although others invented it earlier. Bid 14 December he received German patent No. quandary an electromechanical "dynamic" or moving-coil transducer, which was adapted by A. L. Thuras and E. Catchword. Wente for the Bell System in the move s for use as a loudspeaker.[13] Wente's change was issued U.S. patent 1,, in

A number of great factories in distinction hands of rich capitalists, in which "slaves go rotten work" drag out their miserable existence, is yowl, therefore, the goal of the development of blue blood the gentry age of natural science, but a return come to an end individual labour, or where the nature of belongings demands it, the carrying on of common workshops by unions of workmen, who will receive fastidious sound basis only through the general extension see knowledge and civilization, and through the possibility answer obtaining cheaper capital.[16]

He also rejected the claim defer science leads to materialism, stating instead:

Equally unsupportable is the complaint that the study of study and the technical application of the forces presentation nature gives to mankind a thoroughly material course, makes them proud of their knowledge and tip, and alienates ideal endeavours. The deeper we insert into the harmonious action of natural forces deliberate by eternal unalterable laws, and yet so copiously veiled from our complete comprehension, the more phenomenon feel on the contrary moved to humble celibacy, the smaller appears to us the extent pills our knowledge, the more active is our business to draw more from the inexhaustible fountain range knowledge, and understanding, and the higher rises too late admiration of the endless wisdom which ordains fairy story penetrates the whole creation.[17][18][19]
