This study unit, one in a series of eight, gives students examples of: (1) how a major business began in the mid-nineteenth century; (2) why and how individuals joined in financing and sharing in the growth of such a firm; and (3) how trademarks and brand names were adopted as a symbol that a firm stood behind and took pride in its goods and services. The unit contains an overview, objectives, learning activities, student handouts, vocabulary, and ways to use economic concepts to understand historical development. Original source documents, photographs, and materials from the Procter and Gamble Archive are used. (SM)
