This case describes the nineteenth century founding by Werner Siemens of the Siemens electrical business in Germany. Werner's dual role as inventor and entrepreneur is explored as he created one of the world's first multinational enterprises, whose growth initially rested on its pioneering role in the new telegraph industry. Werner sent his brothers to open businesses in Great Britain and Russia, and the case explores the advantages and disadvantages of family business as a form of organization, as well as the challenges growing it poses for such family firms.
