#23: The Johnson Family – $18.2 Billion
The Johnson family legacy began when Samuel Curtis Johnson bought Racine Hardware Manufacturing Company’s parquet flooring division and transformed it into S. C. Johnson, laying the foundation for a household product empire.

The company expanded into global markets, starting with floor care, with trusted brands like Ziploc, Windex, and Glade. Over the decades, it remained privately held and family-led, preserving its values and vision. Today, the business stands as a leader in consumer goods worldwide.
