Side A: James Norris Gamble, entrepreneur, industrialist, philanthropist and civic leader, is best known for inventing Procter & Gamble’s Ivory Soap, the “soap that floats,” in 1878. Applying a scientific approach, Gamble transformed P&G into a nationally recognized corporate leader and creator of consumer products for a rapidly growing America. Beyond P&G, Gamble financed early efforts to educate freed southern slaves as an original sponsor of the Freedmen’s Aid Society. Later, he underwrote civil rights leader Mary McLeod Bethune’s work to educate poor African American women. In Cincinnati, Gamble’s philanthropy included endowment of Christ Hospital and the founding of its Institute of Medical Research. Gamble funded completion of University of Cincinnati’s Nippert Stadium in 1924 as a tribute to his late grandson.
