Magdalena Martullo-Blocher inherited a major EMS-Chemie stake from her father in 2003 and simultaneously became the company's operating leader, preserving and expanding an already substantial family chemical business. [1][4]
Her ownership came from an established family fortune
Martullo-Blocher worked at companies including Johnson & Johnson and Rivella before joining EMS in 2001, according to the company's own executive biography. [1]
When her father Christoph Blocher entered Switzerland's Federal Council, he sold his majority EMS-Chemie holding to his four children at the end of 2003, directly transferring the economic base of Magdalena's fortune. [2][4]
Martullo-Blocher took command of EMS at the start of 2004, so the inheritance and her assumption of operating responsibility occurred at essentially the same time. [1][2]
She has actively managed and expanded the inherited platform
Under her leadership EMS sharpened its focus on high-performance polymers, expanded internationally and continued to invest in higher-margin specialty products; 2025 operating income reached CHF 567 million. [2][3]
The evidence supports substantial stewardship and value creation, but the core fortune remains the inherited EMS ownership rather than a new business built independently of family capital. That fits the rubric's inherited-and-materially-expanded anchor. [4][1][3]
