Siemens is leading the digital transformation of the industrial world. Digitalization presents enormous opportunities for Siemens but also places new demands on our business in terms of skills, innovation and speed of change.

Gerhard Cromme

Gerhard Cromme (*1943)

Gerhard Cromme studied law and economics from 1962 to 1971, at the Universities of Münster, Lausanne, Paris and at Harvard University (PMD). A native of Lower Saxony, Cromme began his career with the French industrial group Compagnie de Saint-Gobain. In 1986, he moved to Germany’s Krupp group, initially as CEO of Krupp Stahl AG in Bochum, and later as Chairman of the Management Board of Fried. Krupp AG Hoesch-Krupp in Essen. In 1999, Cromme was one of the initiators of the merger of Krupp and Thyssen to form ThyssenKrupp AG, where he and former Thyssen manager Ekkehard Schulz were joint CEOs until September 2001.

The first years of his term as Chairman of the Supervisory Board were dominated by the handling of the compliance crisis together with a new Managing Board headed by Peter Löscher. By appointing Joe Kaeser President and CEO of Siemens AG in August 2013 and supporting the company’s reorientation under Vision 2020, Gerhard Cromme and the Supervisory Board made an important contribution to stability at Siemens.

Heinrich von Pierer

Heinrich von Pierer (*1941)

Heinrich v. Pierer studied law and economics at the University of Erlangen-Nuremberg, Germany. He joined Siemens in 1969 and began his professional career in the legal department. In 1977, Pierer moved to the power generation company Kraftwerk Union AG (KWU), which was then an independent entity. In 1988, he was appointed head of business administration at KWU, which had then become part of Siemens, and a member of its Group Executive Management. The following year, he was appointed President of KWU and a member of the Managing Board of Siemens AG. Pierer was appointed to Siemens’ Corporate Executive Committee in 1990 and Deputy Chairman of its Managing Board in 1991. He served as President and Chief Executive Officer of Siemens AG from October 1, 1992, to January 27, 2005.


With Pierer at the helm, Siemens was transformed from a company that was largely focused on public-sector customers in regulated markets into a global competitor that was increasingly forced to meet shareholder expectations. Under his leadership, sweeping programs were introduced to master this transition. These programs culminated in the Siemens Management System with three key strategic topics – innovation, customer focus and global competitiveness – and in a set of concrete management tools whose application was mandatory company-wide. Pierer also ensured that Siemens’ business portfolio was continually reviewed. All businesses were to occupy leading market positions. If a unit didn’t perform as expected, there were only five options: fix, buy, cooperate, sell or close. 


Pierer was elected to the Supervisory Board at the Annual Shareholders’ Meeting on January 27, 2005, and held the position of Supervisory Board Chairman until April 25, 2007.
