Kirsten Rausing inherited one-third of Tetra Laval with her brothers and has remained involved in family-company governance while also building a separate career in thoroughbred breeding. [1][2]
Her billionaire wealth comes from the Rausing packaging fortune
Forbes says Kirsten Rausing owns one-third of Tetra Laval and that her grandfather founded Tetra Pak, whose packaging technology created the foundation of the family fortune. [1]
Forbes further notes that her father Gad bought out his brother Hans in 1995 for an estimated $7 billion before ownership passed to Kirsten and her brothers Finn and Jörn. [1]
That lineage makes inherited ownership of an established family company the dominant economic source of Kirsten Rausing's billionaire wealth. [1]
She has maintained active governance and an independent breeding career
Tetra Laval's annual report says Kirsten served as an alternate director from 1985 and a non-executive director from 1991, showing long-running participation in family-company governance. [2]
The same report documents extensive leadership in thoroughbred breeding organizations, while Forbes describes her as an award-winning horse breeder, but those activities do not appear to rival the inherited Tetra Laval stake as the source of her billionaire-scale wealth. [2][1]
