The day the first undersea cable was laid across the Atlantic – level 3
The first undersea telegraph cable was laid across the Atlantic on August 5, 1858, connecting North America and Europe.
The cable was 4,600 kilometers long and consisted of seven copper wires insulated with rubber.
The cable was laid by two ships which met in the middle of the Atlantic to connect the two ends of the cable.
The first message sent across the Atlantic via the cable was a letter of congratulations from Queen Victoria to US President James Buchanan.
Unfortunately, the cable functioned for only three weeks before it failed.
What technological developments led to the success of telegraph cables across the Atlantic in later years?
