The idea of using electricity to communicate over distance is said to have occurred to Samuel F.B. Morse during a conversation aboard the ship when he returned from Europe in 1832. The U.S. Government wanted a communication system along its entire Atlantic coast and offered a prize of $30,000 ($767,000 today) for a workable proposal.
By December 1837, Morse had enough confidence in his new system to apply for the federal government's appropriation. He conducted demonstrations of his Telegraph in New York and Washington the following year.
However, when the economic disaster known as the Panic of 1837 took hold of the nation and caused a long depression, Morse was forced to wait for better times. During this period, Morse revisited Europe, tried to secure patent protection overseas, and examined competing telegraph systems in England. After meeting Charles Wheatstone, the inventor of one such electric telegraph system, Morse realized that although his main competitor had built an ingenious mechanism, his design was far simpler, more efficient, and easier to use.
Morse had hired the ingenious construction engineer Ezra Cornell to lay the pipe carrying the wire. Although Cornell did his job superbly, one of Morse's partners, Congressman F.O.J. Smith, had purchased wire with defective insulation. Too much time had been wasted laying bad wire, and with the project on a rigid deadline, something had to be done quickly. Cornell suggested that the fastest and cheapest way of connecting Washington and Baltimore was to string wires overhead on trees and poles. The desperate Morse gave the go-ahead, and the line was completed in time for the dramatic and spectacularly successful link between the Supreme Court chamber of the Capitol building and the railroad station in Baltimore.
Morse electrically transmitted his famous message "What hath God wrought?" from Washington to Baltimore on May 24, 1844.

The Telegraph, which received its first practical demonstration in 1844, came to Chicago in 1848. Telegraphy made possible instant communication with the East Coast and eventually with the entire country.
Daily newspapers began publishing next-day accounts of speeches, elections, and battles furnished by the Telegraph. During the Great Chicago Fire of 1871, a telegram from the mayor brought fire-fighting equipment from Milwaukee; when it was over, citizens lined up at a makeshift Western Union office to inform alarmed friends and relatives that they had survived.

The period from 1866 through 1900 was the apex of Western Union's telegraph power. Yearly messages sent over its lines nationally increased from 5.8 million in 1867 to 63.2 million in 1900. Over the same period, transmission rates fell from an average of $1.09 to 30¢ per message. Even with these lower prices, roughly 30¢ to 40¢ of every dollar revenue was net profit for the company. Western Union faced three threats during this period: increased government regulation, new entrants into the field of telegraphy, and new competition from the telephone.
In 1869 private line service became available in Chicago. The American District Telegraph Company soon offered affluent Chicagoans a home service, allowing them to summon a firefighter, private policeman, or messenger. Telegraphic communication with other Chicagoans was facilitated by the company's network of neighborhood offices and messengers.
In 1880 the Chicago Police Department began using call boxes on the streets. Citizens could report crimes only after obtaining keys to the boxes, which were selectively distributed; relatively few crime reports were made. More importantly, the boxes facilitated official communication among the police. Patrolmen were obliged to make hourly "duty calls" and were thus subject to stricter supervision. They could also summon a paddy wagon if they made an arrest. The call boxes used an innovative combination of telegraphic signaling for periodic messages and the telephone for unusual messages, a design adopted by police departments nationwide.

By 1940 Chicago had more than one million telephones in use, and 90 percent of fire alarms were telephoned to the Fire Department. Portable two-way radios finally rendered police call boxes obsolete, while other forms of telegraphy were largely superseded by more advanced electronic communications.
