  2. What do you see? When was this image taken? What is happening in this picture?

  3. What do you see? When was this image taken? What is happening in this picture?

  4. What are the similarities and the differences in these two pictures?

  5. What are these two pictures called? _______ _______

  6. What are these two pictures called? PrimarySources

  7. Why do we use Primary Sources?

  8. Primary sources provide a window into the past—unfiltered access to the record of artistic, social, scientific and political thought and achievement during the specific period under study, produced by people who lived during that period.

  9. Who were the two people in the pictures?

  12. Today, most people have a computer in their home. They are an integral part of our everyday lives and help us accomplish the most simple of tasks, right down to getting a needed phone number. Do we really appreciate and know how the computer was first developed and where it came from?

  13. IT STARTED WITH THE TYPEWRITER… Before the computer and electricity there was the typewriter. There were many contributors to this invention, so there can be no credit given to any single person. The history of the typewriter starts in 1714 with Henry Mill, British Inventor, who obtained a patent for what was a similar invention to the typewriter.

  14. From 1829 to 1870 many inventors tried to patent a typing device in both Europe and America. However, none of these patents/inventions went into commercial production. Some of these inventors include Henry Mill (a British Inventor) and William Austin Burt (a American inventor, legislator, surveyor, and millwright).

  15. In 1870 a Danish inventor Rasmus Malling-Hansen became the first person to commercially sell the typewriter in 1870 and in that same year Thomas Edison invented the first electric typewriter. Inventors spent years working to perfect this, only to see newer technology make it obsolete. Just like the model T did to the horse and carriage.

  16. Adults were not the only ones who were typing!

  22. THE FIRST COMPUTER DEVELOPED… Charles Babbage, also known as “the father of computing,” originated the idea of a programmable computer. Babbage’s engines were among the first mechanical computers, although they were not actually completed, largely because of funding problems and personality issues.

  23. He directed the building of some steam-powered machines that achieved some success, suggesting that calculations could be mechanized. Although Babbage’s machines were mechanical and unwieldy, their basic architecture was very similar to a modern computer. The data and program memory were separated, operation was instruction based, the control unit could make conditional jumps and the machine had a separate in/output unit.”

  24. The Atanasoff Berry Computer (AKA ABC) was the first electronic Computer. It weighed more than 700 pounds. Work began on this computer in 1937 by John Vincent Atanasaoff and Clifford Berry. This new machine was capable of solving up to 29 simultaneous linear equations. However, the input/output was unreliable and its inventors had to leave Iowa State University for World War II in 1942, leaving the progress of their project untouched.

  25. Because the inventors had left for war they were not widely known until the machine was rediscovered in the 1960’s which caused the controversy of the first computer. “The ABC first demonstrated in 1939 may not have been much of a computer, just as the Wrights’ model was not much of an airplane, but it opened the way.” Allan R. Mackintosh, Professor University of Copenhagen.

  26. Computers small enough for your home The Apple Macintosh debuts in 1984. It features a simple, graphical interface, uses the 8-MHz, 32-bit Motorola 68000 CPU, and has a built-in 9-inch black and white screen.

  29. THE PORTABLE COMPUTER… Early scientists said “computers will never be small enough to be portable” The Epson HX-20 was considered first portable computer (AKA Laptop, Notebook) was developed in 1981. It was the size of a sewing machine and was not battery operated.
