1. Vol 1 The History of Morse Code — Vol 1: The Spark, the Wire, and the Men (1837–1844) How a portrait painter, a machinist's son, and a physicist's electromagnet put the first sentence onto a wire — and which parts of that famous story are actually true.
2. Vol 2 The History of Morse Code — Vol 2: Two Codes — American Morse and the International Reform There is not one Morse code, there are two. The one you can recite is a German revision of 1848; the one that ran America's landlines for a century is a stranger, faster, spikier thing — and understanding why radio chose one over the other explains the code's whole shape.
3. Vol 3 The History of Morse Code — Vol 3: From Wire to Ether — CQ, SOS, and the Long Goodbye Morse code left the wire, went to sea, saved lives, got romanticized, got debunked, and finally signed off for the last time with the same four words it started with. What it did not do is die.
