The S.C. Johnsons – $28.2B
The S.C. Johnson family should not be mistaken for the other Johnsons on the list! Perhaps you have not heard of this company, but you can bet they have influenced your home in certain ways. S.C. Johnson, the household goods manufacturer, was founded in 1886. Back then, they only dealt in parquet flooring. They eventually developed a great floor wax before going to various products like Glade, Pledge, and even Ziploc! Legal drama ensued when Herbert Johnson died and did not leave a will.
