It was founded by Werner von Siemens on October 12, 1847, based on the telegraph he had invented that used a needle to point to the sequence of letters, instead of using the Morse code.
In 1848, the company built the first long-distance telegraph line in Europe, spanning 500 km from Berlin to Frankfurt am Main. In 1850, the founder's younger brother, Wilhelm von Siemens (also called Sir William 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 opened in St Petersburg, headed by another brother, Carl von Siemens .
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 World War II, Siemens employed Jews and Roma as slave labour and ran its own concentration camp near Auschwitz.
