TODAY IN HSTORY: AUGUST 5

August 5 1858: First transatlantic telegraph cable completed
After several unsuccessful attempts, the first telegraph line across the Atlantic Ocean was completed, a feat accomplished largely through the efforts of American merchant Cyrus West Field.
The telegraph was first developed by Samuel F. B. Morse, an artist-turned-inventor who conceived of the idea of the electric telegraph in 1832. Several European inventors had proposed such a device, but Morse worked independently and by the mid 1830s had built a working telegraph instrument. In the late 1830s, he perfected Morse Code, a set of signals that could represent language in telegraph messages. In May 1844, Morse inaugurated the world’s first commercial telegraph line with the message “What hath God wrought,” sent from the U.S. Capitol to a railroad station in Baltimore. Within a decade, more than 20,000 miles of telegraph cable crisscrossed the country. The rapid communication it made possible greatly aided American expansion, making railroad travel safer as it provided a boost to business conducted across the great distances of a growing United States.

In 1854, Cyrus West Field conceived the idea of the telegraph cable and secured a charter to lay a well-insulated line across the floor of the Atlantic Ocean. Obtaining the aid of British and American naval ships, he made four unsuccessful attempts, beginning in 1857. In July 1858, four British and American vessels–the Agamemnon, the Valorous, the Niagara, and the Gorgon–met in mid-ocean for the fifth attempt. On July 29, the Niagara and the Gorgon, with their load of cable, departed for Trinity Bay, Newfoundland, while the Agamemnon and the Valorous embarked for Valentia, Ireland. By August 5, the cable had been successfully laid, stretching nearly 2,000 miles across the Atlantic at a depth often of more than two miles. On August 16, President James Buchanan and Queen Victoria exchanged formal introductory and complimentary messages. Unfortunately, the cable proved weak and the current insufficient and by the beginning of September had ceased functioning.

Field later raised new funds and made new arrangements. In 1866, the British ship Great Eastern succeeded in laying the first permanent telegraph line across the Atlantic Ocean. Cyrus West Field was the object of much praise on both sides of the Atlantic for his persistence in accomplishing what many thought to be an impossible undertaking. He later promoted other oceanic cables, including telegraph lines that stretched from Hawaii to Asia and Australia.

August 5 1914: First electric traffic signal installed
The world’s first electric traffic signal was put into place on the corner of Euclid Avenue and East 105th Street in Cleveland, Ohio, on this day in 1914.
In the earliest days of the automobile, navigating America’s roads was a chaotic experience, with pedestrians, bicycles, horses and streetcars all competing with motor vehicles for right of way. The problem was alleviated somewhat with the gradual disappearance of horse-drawn carriages, but even before World War I it had become clear that a system of regulations was necessary to keep traffic moving and reduce the number of accidents on the roads. As Christopher Finch writes in his “Highways to Heaven: The AUTO Biography of America” (1992), the first traffic island was put into use in San Francisco, California in 1907; left-hand drive became standard in American cars in 1908; the first center painted dividing line appeared in 1911, in Michigan; and the first “No Left Turn” sign would debut in Buffalo, New York, in 1916.

Various competing claims exist as to who was responsible for the world’s first traffic signal. A device installed in London in 1868 featured two semaphore arms that extended horizontally to signal “stop” and at a 45-degree angle to signal “caution.” In 1912, a Salt Lake City, Utah, police officer named Lester Wire mounted a handmade wooden box with colored red and green lights on a pole, with the wires attached to overhead trolley and light wires. Most prominently, the inventor Garrett Morgan has been given credit for having invented the traffic signal based on his T-shaped design, patented in 1923 and later reportedly sold to General Electric.

Despite Morgan’s greater visibility, the system installed in Cleveland on August 5, 1914, is widely regarded as the first electric traffic signal. Based on a design by James Hoge, who received U.S. patent 1,251,666 for his “Municipal Traffic Control System” in 1918, it consisted of four pairs of red and green lights that served as stop-go indicators, each mounted on a corner post. Wired to a manually operated switch inside a control booth, the system was configured so that conflicting signals were impossible. According to an article in The Motorist, published by the Cleveland Automobile Club in August 1914: “This system is, perhaps, destined to revolutionize the handling of traffic in congested city streets and should be seriously considered by traffic committees for general adoption.”
