Franklin A. Guthrie writes to Theodore Roosevelt concerning his scientific invention, and asks if he or anyone he knows would be willing to sponsor his work. The then-Chief of Engineers of the War Department, Alexander Mackenzie, had acknowledged Guthrie’s work. He only wishes for a small pension so that he can commit the final years of his life to servicing in the interest of the country and future generations.
