Tin can telephone -

Before the invention of the electromagnetic telephone, there were mechanical acoustic devices for transmitting spoken words and music over a distance greater than that of normal speech. One of these was the rudimentary tin can telephone, a type of acoustic (non-electrical) speech-transmitting device made up of two tin cans attached to either end of a taut string or wire.

Johann Philipp Reis (1834–1874) -

However, the term "telephone" had been applied to other inventions several years before Bell's breakthrough. German scientist Johann Philipp Reis used the term in reference to his invention, commonly known as the Reis telephone, around 1860.

Elisha Gray (1835–1901) -

The debate about whether Bell was in fact the inventor of the telephone continues to this day. Besides Johann Philipp Reis, Belgium-born Charles Bourseul and the Italian Antonio Meucci have all been credited with the invention. But it's the American electrical engineer Elisha Gray (pictured) that some historians believe should have been awarded the lucrative patent for his development of a telephone prototype in 1876.

Is this the first telephone? -

That said, Antonio Meucci's voice-communication apparatus is also credited by several sources as the first telephone. His 1871 patent for the device was rejected.

Antonio Meucci (1808–1889) -

On June 11, 2002, Meucci was somewhat belatedly recognized for "...his work in the invention of the telephone" (but not "...for inventing the telephone") by the United States House of Representatives.

The telephone goes to war -

In the static trench warfare that prevailed in the First World War, a web of telephone and telegraph wires crisscrossed the battlefields and the areas behind the front lines, allowing real-time conversations. The telephone proved equally vital during the 1939–45 conflict. Pictured are US Army Signal Corps using captured German telephone equipment, around 1916.

International direct dialing -

By the late 1950s, the long-distance telephone call was no longer a luxury. International direct dialing from London to Paris was first offered in March 1963; by mid-1968, transatlantic cable capacity had increased to the point where scheduling calls between Western Europe, the UK, and the USA was no longer necessary and calls were completed on demand.

Cell phone recycling -

Rapid technology change is one reason for the high turnover of cell phone models—millions of cell phones each year are discarded in favor of newer technology. Considered hazardous waste in most countries around the world, disposing of unwanted mobile devices properly has always proved difficult. Organizations like recyclenow offer solutions on how to dispose of unwanted cell phones in a responsible manner. Pictured: old and unwanted cell phones collected for recycling.
