Siemens Healthcare (formerly Siemens Medical Solutions, formerly Siemens Medical Systems) is a medical device supplier to the healthcare industry and is headquartered in Erlangen, Germany. The company dates its early beginnings in 1847 to a small family business in Berlin, co-founded by Ernst Werner von Siemens. Siemens Healthcare is connected to the larger corporation, Siemens AG, which besides healthcare, consists of three other sectors: industry, energy, infrastructure and cities. The name Siemens Medical Solutions was adopted in 2001, and the change to Siemens Healthcare was made in 2008. In 2015, Siemens named Bernd Montag as its new global CEO. 
President and Head of Siemens Healthcare North America is David Pacitti, who replaced Gregory Sorensen, MD.
Globally the company has 43,000 employees, most of them in Germany (comparing to 46,000 at GE Healthcare and 33,000 at Philips Healthcare) and 17.2 billion US-$ sales in 2007 (16.997 billion US-$ for GE).
The history of Siemens Healthcare 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 a new innovative 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 October 12.
Three years previously, in 1844, Werner von Siemens put one of his inventions to use for medical purposes for the first time, using electricity to treat his brother Friedrich for tooth pain. After teaming up with Halske, the new company’s products included electromedical equipment. In Erlangen, Erwin Moritz Reiniger laid the cornerstone for Reiniger, Gebbert & Schall, a company specializing in medical technology.
