Blaise Pascal
Created the Pascaline in 1645 but it did not work because of unreliable parts. http://commons.wikimedia.org/wiki/File:Blaise_Pascal_1423.jpg -
Gottfried Leibnets
Created the Stepped Reckoner in1674 but it also had unreliable parts and therefore it failed. http://commons.wikimedia.org/wiki/File:Gottfried_Wilhelm_von_Leibniz.jpg -
Charles Babbage A.K.A Father of Computers
He used the same four parts as the modern computer; input,microprocessor, storage, and output. https://en.m.wikipedia.org/wiki/File:Charles_Babbage_1860.jpg -
Jaquards Loom
Used cards with holes to make intricate patterns with thread. This idea was later used by Charles Babbage to program computers. http://commons.wikimedia.org/wiki/File:Jacquard_loom,_4_of_6.jpg -
Lady Augusta Ada Countess of Lovelace
Her notes were published and she was called the first computer programmer. http://commons.wikimedia.org/wiki/File:Ada_lovelace.jpg -
Alexander Graham Bell
He invented the telephone which has evolved into tiny computers. We have him to thank for all the phones we have today.

Herman Hollerith
Created a machine that allowed people to calculate the census much faster and had reliable electronic parts. http://en.wikipedia.org/wiki/Herman_Hollerith -
Dr,Grace Murray Hopper
She made the term computer bug when a moth flew in a vacuum tube and shorted out the entire machine. http://commons.wikimedia.org/wiki/File:Grace_Hopper.jpg -
Atanasoff-Berry computer
This was the first electronic digital computer. This design was supposedly stolen from them by the makers of ENIAC. http://commons.wikimedia.org/wiki/File:Atanasoff-Berry_Computer.jpg -
ENIAC
This computer filled a room that was 50x30. With this extreme sizecame the ability to make 50,000 additions a minute. This computer was one of the earliest electronic computers. http://commons.wikimedia.org/wiki/File:ENIAC_Penn1.jpg -

Vacuum tubes
The first gen. of computers. they were fast switches or amplifiers that allowed to multiply 1,000 times faster. https://commons.wikimedia.org/wiki/File:Elektronenroehren-auswahl.jpg -
Transistor
This made computers smaller, faster, cheaper,and more reliable. http://commons.wikimedia.org/wiki/File:Transistors-white.jpg -
Integrated Circuits
By hooking transistors together to make computers faster, much cheaper, and more reliable. http://www.circuitstoday.com/integrated-circuits-merits-and-demerits -
microprocessor
We still use these to this day. They are microscopic computer parts that are extremely efficient. http://commons.wikimedia.org/wiki/File:Ignite_Ia_microprocessor.JPG -
Steve Jobs
Steve Jobs created Apple in 1977 in his garage. He and Steve Wozniak created their first computer, but it was turned down. http://commons.wikimedia.org/wiki/File:Steve_Jobs_Headshot_2010-CROP2.jpg -
