Morse Part 2
As he was not the only one doing research in this field, he had to be quick.
At the same time the German scientists Wilhelm Weber and Carl Friedrich Gauß were working on a similar project. Finally, Morse won out and presented the world’s first electrical telegraph on 4th September 1837.
From an easel, a pen, old parts of a clock and a pendulum, he made a still quite bulky machine. But the basic function was relatively simple: when no current was flowing, the pen drew a straight line. When current was flowing, the pendulum swung out and a spike appeared in the line.
