On 115 years ago today, April 14, 1910 (March 5, 1910 in the lunar calendar), the United States laid the first submarine cable. Workers lay the first submarine cable In 1910, workers put the first submarine cable into the Eske River in Whitby. These people seem to bend their strong bodies and bow to the person in front of them, which is a bit like the relationship between lords and servants in feudal times. This is simply a misunderstanding caused by the image itself. In fact, American workers at the time generally had more rights than their counterparts in other parts of the world. The cables they installed are also ushering in an era from early industrialization to modern industry.
