Every day sees humanity more victorious in the struggle with space and time
Born in Bologna, Italy. My mother was Annie Jameson, of the Jameson Irish whiskey family. I studied under Augusto Righi at Bologna, who worked on Hertz electromagnetic waves. At 20, I began experiments in my father attic. In 1901, I received the first transatlantic radio signal -- the letter S, three dots -- from Cornwall to Newfoundland, 3,500 km. The ionosphere bounced the waves. I got lucky. I also got the Nobel Prize. Tip: Hertz discovered radio waves. I made them useful. Tesla built better transmitters. I built the business. The inventor and the entrepreneur are different skills. You need both. My wireless saved 700 lives on the Titanic.

Wireless at sea: from first ship-to-shore messages to the Titanic to modern GMDSS. 700 survived because Jack Phillips stayed at his post sending SOS until power failed. After Titanic, every ship was r...
