Biography

Gwendolyn Sontheim Meyer inherited an estimated 8% stake in food giant Cargill.

The heiress spends most of her time on a farm in Rancho Santa Fe, Calif., training horses that compete in show jumping.

Her great-grandfather, W.W. Cargill, the son of a Scottish sea captain, founded Cargill in Conover, Iowa in 1865.

The family still owns roughly 90% of Cargill, which did $154 billion in 2025 sales across food, agriculture, financial and industrial divisions.
