Those who study the history of companies are witnesses to exciting developments; they delve into a succession of highs and lows, successes and failures, economic and social changes. And they become acquainted not only with the founders but also with the people who successfully develop the companies, who guide and lead. This is exactly what unfolds in the new book from the Siemens Historical Institute. Through 13 detailed portraits, the book relates how the more than 170-year history of Siemens is interwoven with the history of Germany, Europe, and the world. From the founder, Werner von Siemens, to Carl Friedrich von Siemens to Joe Kaeser, it is clear that the company needs people at the top who lead with courage, drive, and a sense of responsibility, who are not afraid to face the challenges of the times and to shape the future.
