The Discovery of Electrography.

Prof. Jakob Narkiewicz-Jodko (1947--1905) major discoveries are: Electrography -- the method of the visualization of corona discharge (corona discharge photography) from the bodies due to the application of high strength and high frequency electric fields [1-4], and the first observation of the propagation of the electromagnetic waives for information transfer over the distances [5,6]. They were made in his laboratory, located at his manor home Nadniemen in Eastern Europe. We describe these experiments and equipment used in the Lab for these discoveries. We also introduce a mathematical algorithm for the analysis of the electrography images. [1] Decrespe M.
