The Story of Electricity



Finished The Story of Electricity, published, if I can read Roman numerals correctly, in 1912, although copyrighted in 1902. It's a story, basically, of what can be done with electricity without much for active components. Now, they did have batteries, generators, and a few special purpose tubes at that time, but they generally could not increase the power of a signal (The coherer came close, in that it could use wireless signals of small power to close a circuit of large power, but it was binary and slow.)

(The Audion, an amplifying vacuum tube was invented in 1906, so the state of the art is just at the threshold of power amplification.)
