Scope and Contents note:
Press clippings, 1895-1897, from British publications (some unidentified) and one French journal describing the invention and the organization of the Automatic Telephone Company, Ltd. A note on the life of Max Margowski, one of the company's organizers is included, with statements of the company accounts (one a 1901 balance sheet). A record of litigation, some of it possibly related to the Apostoloff invention, is included in the bound "Transcript of Record from the United States Circuit Court of Appeals for the Third Circuit", March 1930 (457 pages) , which details the suit of the Dubilier Condenser Corporation against the Radio Corporation of America over the previous eight years, concerning the use of certain devices in radio and telephonic communications.
Russian engineer S. B. Apostoloff invented an "automatic" telephone exchange in the late 19th century. It enabled the use of telephones without requiring the services of a human operator through magnetically-actuated switching devices manipulated by the caller. The invention resulted in the organization in London of the Automatic Telephone Company, Ltd. and its reorganization two years later.
