In the latter half of the nineteenth century Hertz began his all-important experiments with high voltage sparks which finally culminated in his discovery of the vibration or wave through space which occurred when these sparks took place. These waves through the ether now bear his name. Hertzian waves, they are called, and it is by their use that radio is made possible. Marconi, a very briU iant young man, was much interested in the work that Hertz had been doing, and began experimenting along similar lines himself. After some original and daring experiments in this new field opened out by Hertz swork, Marconi conceived of the idea of an apparatus which would detect the presence of these waves. After many trials he developed a crude apparatus which would do this over small distances. He then started in and, by sheer genius and hard work, gave us the child of his brain which he called the wireless telegraph.
