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 documents for 1914 are letters pertaining to the Deutsches Museum and the Franklin Institute. The German-language items from the Deutsches Museum are accompanied by English translations or abstracts prepared by Swiss-born machinist Charles Nicholaus Wurth.
Less than 5 percent of the documents have been selected, including all documents bearing substantive marginalia by Edison. The following categories of documents have not been selected: requests for Edison's autograph or signature, including its reproduction; form letters and other routine correspondence regarding meetings and activities; invitations and other requests that Edison either declined or did not acknowledge; invitations for which no substantive response has been found; correspondence from organizations in which Edison was not involved; published proceedings and printed circulars; and duplicates.
