The Johnson family founded the American chemical company S. C. Johnson, maker of household brands such as Glade and Raid.
Samuel Curtis Johnson Sr. established the business in 1886 after purchasing a parquet flooring company in Racine, Wisconsin. The company first sold floor-care products before expanding into household chemicals and consumer brands. Its best-known products have included Glade air fresheners, Raid insecticides, and Pledge furniture care.
S. C. Johnson remains privately held and has passed through several generations of the Johnson family. The company is distinct from Johnson & Johnson, the healthcare corporation founded by Robert Wood Johnson, James Wood Johnson, and Edward Mead Johnson in 1886. The similar names are a common source of confusion, but the two companies have different histories and businesses.
