The boys' life of Edison

The narrative traces Thomas Edison's development from curious boyhood experiments through work as a newsboy and telegraph operator to a busy career of invention and enterprise. Chapters describe early mechanical interests, telegraphy training, and episodes that shaped his methods, then turn to landmark inventions and commercial ventures such as improvements to voice transmission, the phonograph, electric lighting and central-station systems, electric railways, motion pictures, cement and storage batteries. Later sections outline his laboratory practices, inventive method, personal habits, and wartime contributions, framed for younger readers with illustrated episodes and autobiographical notes.
