This folder contains documents, primarily correspondence, covering a wide variety of subjects. Some of the material relates to personal matters. Also included are documents that deal with more than one subject, such as a letter about both the electric light and the phonograph. Documents concerning subjects that do not fall under the main subject categories are also filed in this folder. Among the items are correspondence with Henry Villard concerning the formation of a company to manufacture Edison's inventions and a list of proposed research projects. Also included are letters about the rift between Edison and Edward H. Johnson, one of his business associates, and about Edison sending models of several of his inventions to Sir Frederick Bramwell for a lecture before the Royal Institution of Great Britain.
All of the documents have been selected except for duplicate copies of selected documents.
