Any reader expecting this book to consist of a compilation of the so-called “ systems” of Wireless Telegraphy will be deceived. I fail to see that such a compilation would be of use to anyone, believing rather that a simple and comprehensive unfolding of the fundamental principles and working methods of modern telegraphy by means of electric waves is the more appropriate. On these grounds I may claim the right to term my work objective. Besides, I can draw on the abundant store of personal practical experience I was able to gather as manager of the important experimental stations on the Baltic Sea (Sassnitz-Gross-Moellen) for Professor Braun, Siemens & Halske. Hence I hope to create interest in wider circles for this rapidly growing branch of science and technology, as well as to perform some service to those more closely concerned with the subject, by combining theory and practice.
It is for me a welcome duty to offer my thanks in this place to Dr L. Mandelstam, for his advice and skilful co-operation in the most recent attempts to develop a selective system of wireless telegraphy I am also greatly obliged to the Gesellschaft für drahtlose Telegraphie “ Telefunken," of Berlin, for the use of blocks and photographs, and also wish to express my thankfulness to Mr M. G. Fox, for his kind assistance in revising the English style of the manuscript.
