Mr Watson Rides Again
For telecoms the big transistor breakthrough was Lee de Forest’s triode.
In October 1912, de Forest demo-ed it to AT&T.
In 1913 AT&T built it into a phone line between Baltimore and New York.
Then, in 1914, it was built into a coast-to-coast, 3,400 mile long, phone line between New York and San Francisco.
To inaugurate the line, Alexander Graham Bell in New York repeated his famous quote to Thomas Watson in San Francisco: “Mr Watson, come here, I want you.”
This time Watson replied: “It will take me five days to get there now.”Tags: alexander graham bell, breakthrough, demo, transistor
