Robert Hooke's Tin Can Telephone
Some of you may have constructed a tin can phone in elementary school as part of a science experiment, and give yourself extra credit if you remember the name Robert Hooke. Considered one of the most important scientists of the 17th century, Hooke discovered a way to "to hear one speak through a wall a yard thick...I have, by the help of a distended wire, propagated the sound to a very considerable distance in an instant." What a smarty pants. -
Alexander Graham Bell's "Electrical Speech Machine"
Consists of a single transmitter/receiver jammed into a rectangular wooden box. it cannot be fully credited to Bell as he had help from other which with their collected efforts, became one of the most significant inventions of all time. -
Wilhelm Candlestick
Walter Wilhelm, an electrician by trade, improved upon the Butterstamp receiver and every other phone of the time with his double diaphragm design. Wilhelm phones wouldn't be the first to employ essentially two Butterstamp receivers -- one for talking and one for listening -- but unlike other phones of the time, it came with two separate chambers and diaphragms. -
Candlestick model 302
it is the a descendant of the candlestick holder which has evolved from a vertical stand design to lying down horizontally. despite there being previous models that did this, none of them talk the iconic shape this historical phone has. -
Ericsson Mobile Telephone System A
This was the first actual mobile phone. it weighed as much as 88 pounds which is about 300 times more than an iphone. It was commercially available in Sweden and often found permanent installation in vehicles. -
Cordless Phone
The first cordless phone was invented by an African American inventor by the name of Dr. Raymond P. Phillips Sr. He was not recognised as the inventor until 1987. These phones were not used until decades later. -
Motorola (first major commercial phone)
"The DynaTAC cellular system required phone calls to be switched from cell to cell as users traveled," Motorola explains. "Making that happen without a high rate of dropped calls required innovative engineering. And foremost, Motorola had to create a high capacity system that worked with both portable phones and mobile car phones." -
First successful touchscreen phone - iphone
You are probably wondering why this was chosen instead of the first actual touch screen phone. Well its because the iphone was the first phone to have a fine working touch screen along with a user friendly interface. It was this smart phone that pushed competing mobile manufactures to lift their game or be left behind. Applications on phones were made a big deal after this iphone which some would argue has begun a revolution.
