Biography
Marianne Liebmann is one of 21 billionaire heirs to Cargill, America's largest private company.
Her great-grandfather, W.W. Cargill, founded the business as a single grain warehouse on the end of an Iowa railroad line in 1865.
The family still owns roughly 90% of Cargill, which did $154 billion in 2025 sales across food, agriculture, financial and industrial divisions.
The Cargill-MacMillan family collects an estimated 18% of net profits as dividends every year.
