[2] Inspired by the successes of Knoxville's Appalachian Expositions of 1910 and 1911, civic leaders sought to bring greater national exposure to the community with a third exhibition in 1913.President Woodrow Wilson addressed visitors via wireless transmission, and Governor Ben W. Hooper and Mayor Samuel G. Heiskell delivered speeches.[8] Among the visitors were Booker T. Washington, Helen Keller, William Jennings Bryan, Gifford Pinchot, and the Catholic Archbishop of Baltimore, Cardinal Gibbons.The content of the fair was mostly entertainment such as a mock coal mine explosion, moving pictures and John Robinson's "Herd of Trained Elephants".The conservation exhibits talked of progressive topics such as peak coal, the loss of topsoil due to poor farming techniques, and the value of wildlife.
