Apple didn’t invent the mouse. It was built at SRI International by Douglas Engelbart and patented in 1970. Apple licensed it for about $40,000.
Also, Apple wasn’t the first company to attach a mouse to a computer. This had been done by Xerox on their 8010 Star personal computer, which unfortunately wasn’t a success probably because of its steep price, a staggering $16,000.
In addition to being the inventor of modern mouse, Douglas Engelbart is best remembered for giving a live demonstration of several computer technologies at the Fall Joint Computer Conference in San Francisco. This Mother of All Demos took place on 9th December 1968 and showcased windows, hypertext, graphics, video conferencing, word processing and, of course, the mouse.

Contrary to popular belief, Thomas Edison, one of the greatest inventors of all time, didn't invent the light bulb. He simply improved upon it to create a practical, long-lasting incandescent source of light! The light bulb was first demonstrated in 1878 by British physicist Joseph Swan. The inventor used carbonised paper as a filament and patented the bulb in 1880. The next year, London's Savoy Theatre became the world's first public building to be lit by the electric wonder. Edison's genius was to understand the nature of the bulb and painstaking test hundreds of materials as filaments. After many trials, his group finally arrived at a carbon bamboo filament which would not only make the bulb last longer (1,200 hours) but could also be produced cheaply. They demonstrated their light bulb on 31st December 1979. Edison too filed and received a patent for his electric bulb. Including Thomas Edison and Joseph Swan, there were a total of eight inventors working on the electric bulb at that time. [more...]
