[QP021-F] American Graphophone Company v. National Phonograph Company (Macdonald Patents 606,725 and 626,709)

This folder contains material pertaining to two suits brought by the American Graphophone Co. against the National Phonograph Co. in the U.S. Circuit Court for the District of New Jersey. The cases were initiated in March 1905, and each involved one of Thomas H. Macdonald's patents on the composition of wax cylinders. The selected items consist primarily of letters to and from Adolph Melzer, who conducted experiments on wax cylinders for Macdonald during the 1890s. Also included is a 1906 memorandum by Frank L. Dyer informing Edison about the progress of the litigation, along with letters relating to the eventual settlement of the cases in June 1908. Portions of the court record for these two cases appear in Thomas A. Edison Papers, Part III (1887-1898).
