Lee de Forest did not invent the electronic age alone, but his Audion helped make it possible.

In Lee de Forest, Jasper Wilson tells the dramatic and morally complicated story of the inventor whose fragile three element vacuum tube helped transform weak electrical signals into the foundation of modern electronics. Before silicon, before transistors, before chips made electronics invisible, the future glowed inside glass. The Audion began as a radio detector, but its deeper power was amplification, the ability to make faint signals stronger, clearer, and capable of traveling farther than ever before.

This biography follows de Forest through the early world of sparks, antennas, opera broadcasts, patent wars, unstable companies, courtroom battles, and restless ambition. He was brilliant, vain, persistent, reckless, and often unable to control the future his own invention opened. Others improved the Audion, industrialized it, and understood its possibilities more fully, but the device became a crucial ancestor of radio broadcasting, long distance telephony, public address systems, sound film, radar, television, and early electronic computers.

Cinematic, technically clear, and deeply human, Lee de Forest is not a simple story of heroic invention. It is the story of a man who opened the door to the electronic century and then watched corporations, engineers, lawyers, broadcasters, and Hollywood build worlds on the other side. Before the modern world became silicon, it was glass, heat, vacuum, signal, and ambition.
