Rendering of what the restored James N. Gamble House would look like. The Gamble House is the residence most strongly associated with the life and work of James Norris Gamble, a Westwood promoter who, in the course of his work with the family business the Procter & Gamble Company, developed Ivory Soap, a groun-breaking consumer product still in production today. For more than sixty years - from 1871 to 1932 - as James N. Gamble became an admired entrepreneur, industrialist, civic leader, and philanthropist - this is where he called home.
