C. G. McKay, "From the archives: Arvid Damm makes an offer", Cryptologia, 18(3), 1994, pp243-249. Abstract: "The offer from Damm to the Swedish Ministry for Foreign Affairs was located in the Swedish National Archive, Stockholm. It throws some more light on Damm's early exertions in the field and reveals inter alia an attempt before the Great War of 1914--1918 to interest the British authorities in his cipher devices. A.G. Damm and C.L. Craig invited the Swedish State to acquire the sole right within Sweden of using the invention described which hitherto had been only offered to the British Government, and for which a patent had been sought in Germany and Great Britain and later sought in Sweden and other countries. The invention consists of a new method based upon mathematical grounds, for the presentation and decipherment of cryptograms along with the associated devices. The method can be applied to, and the devices are designed for, the diplomatic service, the army and navy and wireless telegraphy".
