Werner von Siemens constructed the pointer telegraph. With this design, he laid the foundation for Siemens & Halske Telegraph Construction Company, which was founded in 1847.
		Werner Siemens discovered the dynamo-electric principle and thus enabled electricity to be put to practical use. The dynamo can convert mechanical energy into electrical energy in an economical way and laid the foundation stone for today's world of electrical engineering.
		Inauguration of the trans-Atlantic cables and building the Indo-European telegraph line from London to Calcutta.
		Differential arc lamp built by the chief designer at Siemens and kicked off the widespread use of urban street lighting.
		The first electric railway was presented at the Berlin Trade Fair.
		The first subway on the European continent was opened in Budapest.
		Siemens installed the first set of automatically operated traffic lights Germany on Berlin's Potsdamer Platz.
		Walter Schottky develops the space charge theory (or Schottky barrier theory), a pioneering breakthrough for semiconductor development.
		Siemens provided the pioneers in echocardiograph with the world's first echocardiograph for research purposes.
		The world's first cardiac pacemaker was developed and produced at Siemens-Elema in Sweden.
		Siemens presents "Simatic", the first electronic control system. Simatic becomes an important element of automation technology.
		World's first high-voltage dc transmission line equipped with thyristors is installed for the Cabora Bassa hydro-electric power station in Mozambique.
		Siemens builds the world's fastest neurocomputer "Synapse 1"
		High-temperature fuel cells with an output of 1.8 kW set a new world record.
		Siemens took fire detector technology an important step further. The Sinteso fire detectors have a number of sensors which are linked with intelligent evaluation technology which analyses the signals, evaluates them and assesses the situation. False.
		SOMATOM Definition - faster than any beating heart. This computed tomography (CT) system records images with unprecedented resolution and speed, and uses up to 50 percent less radiation.
