Ulrike von Baumbach

Ulrike von Baumbach derives her wealth from Boehringer Ingelheim, the world's largest private pharmaceutical company.

Founded in 1885 by Albert Boehringer, the company supplied ingredients to pharmacies, textile merchants and the food industry, and grew to a workforce of 1,500 by the time of his death.

In 1917 the company opened a research department with chemist Heinrich Wieland, Boehringer's cousin, who went on to win the Nobel Prize in Chemistry.

Today, Boehringer Ingelheim's most well-known drugs treat COPD, anti-coagulation and type 2 diabetes; it now employs 53,000 people and has a presence in 130 markets.

Von Baumbach along with 14 members of the family own equal parts of the company.
