Introduction to Marconi’s Nobel Lecture

V Rajaraman

It is now a century since the first transcontinental wireless transmission when Guglielmo Marconi received wireless signals across the Atlantic in December 1901. ...  He shared the Nobel Prize with Karl Ferdinand Braun who modified Marconi’s wireless transmitters significantly to increase their range and usefulness.

Wireless Telegraphic Communication

Guglielmo Marconi

The discoveries connected with the propagation of electric waves over long distances and the practical applications of telegraphy through space, which have gained for me the high honour of sharing the Nobel Prize for Physics, have been to a great extent the results of one another.

The application of electric waves to the purposes of wireless telegraphic communication between distant parts of the earth, and the experiments which I have been fortunate enough to be able to carry out on a larger scale than is attainable in ordinary laboratories, have made it possible to investigate phenomena and note results often novel and unexpected. In my opinion many facts connected with the transmission of electric waves over great distances still await a satisfactory explanation, and I hope to be able in this lecture to refer to some observations, which appear to require the attention of physicists.
