Interior of One of the Tanks on Board the Great Eastern: The Cable Passing Out

One of the 19th century's great technological achievements was to lay a telegraphic cable beneath the Atlantic, allowing messages to speed back and forth between North America and Europe in minutes, rather than ten or twelve days by steamer. An initially successful attempt in 1858, led by Cyrus W. Field and financed by the Atlantic Telegraph Company, failed after three weeks. Two working cables were finally laid in July and September 1866, the result of repeated efforts by the indefatigable Field, a cadre of engineers, technicians, and sailors, two groups of financial backers, and significant help from the British and United States navies. This watercolor by Dudley shows one of the three huge tanks inside the hull of the Great Eastern used to transport 2,400 nautical miles of coiled cable. Part of a series documenting the long, arduous process, this image was reproduced as a color lithograph in William H. Russell's 1866 book "The Atlantic Telegraph" (92.10.100 and 61.536.5). In 1892 Field donated art works by Dudley, a copy of Russell's book, commemorative medals, memorabilia, and specimens of cable to the Museum.
