The first attempt at laying a transatlantic telegraph cable was promoted by [[Cyrus West Field]], who persuaded British industrialists to fund and lay one in 1858.<ref name="guarnieri 7-1"/> However, the technology of the day was not capable of supporting the project; it was plagued with problems from the outset, and was in operation for only a month. Subsequent attempts in 1865 and 1866 with the world's largest steamship, the [[SS Great Eastern|SS ''Great Eastern'']], used a more advanced technology and produced the first successful transatlantic cable. ''Great Eastern'' later went on to lay the first cable reaching to India from Aden, Yemen, in 1870.
