This folder contains letters congratulating Edison on the celebration of his sixty-ninth birthday. Among the items for 1916 is a letter from journalist John A. Sleicher reminiscing about Edison's demonstration of his tinfoil phonograph in January 1878 at the Western Union headquarters in New York. Also included are letters from longtime Edison associates Sidney B. Paine, manager of the Mill Power Dept. at General Electric's Boston office, and Frederick A. Scheffler.
Less than 5 percent of the documents have been selected. Most of the items not selected received no response from Edison. Some bear his marginalia, indicating the reply of a simple "thanks."
