Side A: Begun as a partnership between candle maker William Procter and soap maker James Gamble in 1837, Procter & Gamble (P&G) grew from its roots to become one of the world’s largest and best-known consumer products companies. Building on Civil War candle and soap contracts, P&G grew rapidly by nationally marketing its floating Ivory Soap (1879). Innovative product research and creative marketing techniques resulted in the development of dozens of successful, universally recognized brands and expansion into beauty care, paper, and health care products. Its worldwide headquarters remains in Cincinnati.
