161 years ago, Thursday, October 24, 1861 during the early months of the War Between the States, the first transcontinental electric-telegraph line was completed by the Western Union Telegraph Company when the Eastern & Western sections were connected together at the telegraph office in Salt Lake City in Utah Territory, after which California Chief Justice, Stephen Johnson Field (1816-1899), wired a congratulatory message from San Francisco, California to U.S. President Abraham Lincoln (1809-1865) in Washington, D.C.
It is noteworthy that the Pony Express (1860-1861), which boasted that it could deliver a letter from Sacramento to St. Joseph, Missouri in the unheard-of time of 10 days, was instantly made obsolete & went out of business on October 26, 1861 -- two days after the transcontinental electric telegraph system went live.
The circa-1862 photograph depicts the site where the Eastern & Western sections of the transcontinental telegraph were joined at the telegraph office on the East side of Main Street in Salt Lake City, Utah Territory.
