Wolfgang Marguerre Net Worth

Wolfgang Marguerre has an estimated net worth of $7.5 billion, according to Forbes Real-Time Billionaires, Wolfgang Marguerre profile (figures as of October 20, 2026). That is up from $5.1 billion in 2019.

Wolfgang Marguerre is a German businessman who founded and owns the Octapharma Group, one of the world's largest makers of blood plasma products. Born in 1941 and raised in Heidelberg, he studied political and economic science at Heidelberg University and earned an MBA at INSEAD in 1972. Forbes counts him as a self-made billionaire.

Before starting his own company, Marguerre spent years in healthcare management. He ran Pharmaplast in Copenhagen, then worked at Baxter-Travenol Europe in Brussels. In 1979 he became senior executive vice president of the Revlon Healthcare Group in Paris. He left that job in 1983 to found Octapharma in Switzerland with Robert Taub. The name comes from the Greek word for eight, a nod to the factor missing in people with hemophilia A.

How Octapharma made Marguerre rich

Octapharma makes medicines from human proteins, used in hematology, immunotherapy, intensive care and emergency medicine. Plasma products are a lucrative market, and the company has grown to a large scale. Forbes reports that it runs production plants in six countries, employs more than 11,000 people and brings in yearly revenue of more than 3 billion euros. It also has about 200 donation centers that collect plasma.

Ownership is kept in the family. Marguerre and his three children own Octapharma, and two of his sons, Frederic and Tobias, sit on the management board. Because the company is private and controlled by the family, his fortune is tied directly to the value of the business. The company also sponsors Save One Life, a nonprofit that helps children and adults with blood disorders.

How his Forbes estimate has changed

Forbes valued Marguerre at $5.1 billion in 2019 and $5.5 billion in 2020. His estimate then surged to $9.1 billion in 2021, the highest figure in his Forbes history so far. The figure came back down to $5.2 billion in 2022 and settled at $5.5 billion in 2023, then rose to $6.4 billion in 2024.

His fortune has kept growing since. Forbes put him at $6.2 billion in 2025 and $7.9 billion on its 2026 World's Billionaires List. As of October 20, 2026, its real-time billionaires tracker showed $7.5 billion. Marguerre is also a supporter of the arts. He gave $17.5 million to renovate Theater Heidelberg, and its new stage was named Marguerre Hall when the theater reopened in 2012.
