Policeman Electrocuted By Phone In Philadelphia
The telephone was invented by Alexander Graham Bell in 1876. The next year the first police telephone was installed in Albany, New York. Call boxes for use by both police and members of the public were first installed in Washington, DC in 1883, in Chicago and Detroit in 1884 and in Boston in 1885. These were direct line telephones placed on a post which could often be accessed by a key or breaking a glass panel. In Chicago, the telephones were restricted to police use, but the boxes also contained a dial mechanism which members of the public could use to signal different types of alarms.
