Werner von Siemens

Ernst Werner Siemens, known as Werner von Siemens after 1888, was a German electrical engineer, inventor, and industrialist. He was born on December 13, 1816, and passed away on December 6, 1892. Siemens made many important contributions to the world of electricity and engineering.

He founded the company Siemens, which grew into a large business focused on electrical and telecommunications technology. Siemens invented several key technologies, including the electric tram, trolley bus, electric locomotive, and electric elevator. His work helped shape the modern use of electricity.

One of his most important inventions was the dynamo, a machine that produces electricity. This invention was crucial for the development of the modern age of electricity. Siemens also played a role in the early development of the electric car. Because of his many contributions to electrical science, the unit of electrical conductance is named the siemens in his honor.

Biography

Ernst Werner Siemens was born in Lenthe, near Hannover, in the Kingdom of Hanover. After finishing school, he joined the Prussian Military Academy because his family could not afford school fees. There, he helped develop electrically-charged sea mines used in war.

Siemens later focused on improving existing technologies. In 1847, he founded the company Telegraphen-Bauanstalt von Siemens & Halske, which grew into a worldwide business. He invented a telegraph that used a needle instead of Morse code. Over time, his company made many important advances in technology.

In later years, Siemens built the world's first electric passenger train in 1879 and the first electric elevator in 1880. His company also created the first electric tram in 1881 and tested the first trolleybus in 1882.

U.S. patents

Werner von Siemens received several important patents in the United States. These include inventions for electric railways, which helped create trains powered by electricity, and electric meters, which measure how much electricity is used.
