Audion Tube
In 1906, Lee DeForest, created (or 'borrowed' the idea for) the audion tube. The audion tube was a vaccum tube that amplified signals. It is widely believed that a Canadian inventor, Reginold Fessenden, actually came up with the idea, but Fessenden didn't seem to make it into the history books for that invention. -
Iceberg Straight Ahead!
Marconi sells radio to the marines. He dpes this because before radio, if anything were to happen to your ship, no one outside of the people on board would realize anything actually happened until weeks after the event.So when the titanic sank, if they didn't have radio, then everybody would have died. -
