The history of Siemens Healthineers started in Berlin in the mid-19th century as a part of what is now known as Siemens AG. Siemens & Halske was founded by Werner von Siemens and Johann Georg Halske on 12 October 1847. The company formed around an invention created by Siemens called the pointer telegraph. Based on the telegraph, Werner von Siemens' new invention used a needle to point to the sequence of letters, instead of using Morse code. The company, then called Telegraphen-Bauanstalt von Siemens & Halske, opened its first workshop on 12 October. Eventually, the new company included electrometrical equipment and specialized in medical technology.
