wireless telegraph by Marconi

Until the advent of electrical communications with the invention of the telegraph by Samuel F. B. Morse in 1835, human communications was limited to as far as one could see or as fast as a horse could run. Applying the electrical principles developed by the physicists preceding him (as presented in the Fundamentals Gallery) Morse was able to move human communications in one step to the speed of light by sending signals over wire. However, this was only the beginning as electrical and electronics advances moved communications from telegraph to voice and eventually to wireless pictures, television, and digital communications. Here you will see that development chronicled and how the military was quick to adopt these new capabilities.
