Brigadier General A.S. Daggett to R.E. Ely, March 16, 1907
While the letters are on a number of different topics, many deal with the Sterling Debenture Corporation and stock offerings in the American Telegraphone Corporation. The corporation was founded in 1903 to manufacture the Telegraphone, a magnetic sound recording device invented by Danish engineer Valdemar Poulson. Although several hundred machines were bought by curious scientists, the product was not a commercial success.
