This collection houses personal and professional papers of George P. Palo, former Chief Engineer of the TVA, and his wife, Annie G. Palo. The bulk of the collection consists of materials documenting Palo's work at the TVA and correspondence from William McCall and wife, Gretchen Schweitzer McCall, in which McCall discusses his life's work in education and his memoir, I Thunk Me a Thaut. These papers also include correspondence from Palo's family, papers detailing the Palo family's history, and materials documenting George and Annie Palo's extensive travels. There are also loose photographs (many showing George and Annie Palo with unidentified others) as well as a photo album depicting the Palos and various dignitaries and delegates at the World Power Conference in Vienna in 1956.
