In 1820, Charles Xavier Thomas de Colmar, a French mathematician, created the first commercially successful mechanical calculator. The "Arithmometer" could perform the 4 operations. The idea came across Thomas de Colmar while he was serving in the French Army where he had to do a great deal of calculations. http://www.youtube.com/watch?v=h8DVTAeyXK4

The Difference Engine is an automatic, mechanical calculator using the decimal number system. This machine was powered by cranking a handle. The British Government took interest in Babbage's machine as producing tables was time-consuming and expensive. This engine was initailly built to tabulate polynomial functions, or divided differences. http://www.youtube.com/watch?v=B8tmfcOg8l8

The Analytical Engine has many essential features found in the modern digital computer. This machine was proposed as the first general-purpose computer. Babbage decided that the his previous creation, the Difference engine was too complicated, a more simple design was possible.The input (programs and data) was to be provided to the machine via punched cards. There was to be a memory capable of holding 1000 numbers of 40 decimal places each. http://www.youtube.com/watch?v=IGuBYrvS9wY

Samuel Morse proves that signals can be transmitted through wires How it worked: pulses of current would move a marker which would produce written codes on a strip of paper. This was called the Morse Code http://www.youtube.com/watch?v=Lki3jxNLVCI

Ada Lovelace wrote the first published description of a stepwise sequence of operations for solving certain mathematical problems. She collaborated with Charles Babbage to develop and enhance the Anayltical Enigine. Ada’s notes explained how the Engine differed from the original Difference Engine.Because of this, she is credited as the first computer programmer. http://www.youtube.com/watch?v=NPDsaZkVsFc

The QWERTY keyboard is still used today on laptops, comupters and other elctroncial devices. Christopher Latham Sholes, the inventor of the keyboard, built the first version with many flaws. One of them being that the letters were too close together, it was clumsy and often led to jamming. Sholes struggled for 5 years before perfecting the QWERTY keyboard. http://www.youtube.com/watch?v=PbAnMlqpp4o

Alexander Graham Bell was the first credited man for the electric telephone. However, he was not the only working on it. Many other engineers were invovled in the making of the telephone. The early history of the telephone became and still remains a confusing morass of claims and counterclaims. http://www.youtube.com/watch?v=qWUP9EigdjY

Thomas Edison intorduced the first phonograph, a machine that could both record and reproduce sound - similar to the modern recorder. Scratches, grooves and engraved marks would be on the disc and would project sound out of the mouth. http://www.youtube.com/watch?v=Wmg0BD_rR6Y

Henry Babbage, Charles Babbage's youngest son, completes a portion of the anayltical machine and was able to perform simple calculations. Henry built an experimental four-function calculator for the Mill for the Analytical Engine, completing it in 1910 when he was eighty-six years old. http://www.youtube.com/watch?v=1NRXOGVC9ts

Paul Eisler invents the Printed Circuit Board (PCB) while working on a radio. Around 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. Later on, the USA released the invention, allowing commerical use.
Now, PCBs are used for computers, tablets, phones, mouses and many more. -
Konrad Zuse introduces the Z3, the world's first working programmable, fully automatic computing machine. Program code and data were stored on punched film. The Z3 was built with 2,000 relays, implementing a 22 bit word length that operated at a clock frequency of about 5–10 Hz. http://www.youtube.com/watch?v=QRAkPF7Npj4
