This folder contains correspondence and other documents relating to Edison's membership in, and activities on behalf of, social clubs, professional societies, political groups, and civic organizations. There are also appeals from charitable organizations. Among the items for 1915 is a communication from Charles P. Steinmetz regarding Edison's election as an honorary member of the Illuminating Engineering Society, as well as a letter from engineer Henry M. Byllesby asking him to serve on the advisory committee of the Tariff Commission League.
