  • Martin Cooper, who turns 82 on December 26th, is an electrical engineer – having gained his Master’s degree from the Illinois Institute of Technology in 1957.
  • Cooper’s inspiration for undertaking the project was the Star Trek television series, in which a small, hand-held ”communicator” device was used very much in the manner of a portable phone.
  • As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973 there weren’t cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter – probably one of the more dangerous things I have ever done in my life.

  • Interestingly, the first person he called was Joel Engel, his chief rival at AT&T’s Bell Labs, to tell him he was calling on a portable phone.
  • The original phone weighed a gargantuan 30 ounces, and was referred to as the “Brick.”
  • With nearly four decades of success in the telecommunications industry, Cooper’s guiding philosophy is to look to its bright future: It’s very exciting to be a part of a movement toward making broadband available to people with the same freedom to be anywhere that they have for voice communications today. People rely heavily on the Internet for their work, entertainment, and communication, but they need to be unleashed.

    This is a very good biography about Martin Cooper and the invention of the cell phone. It also has some pictures of him, the phone, and also one of Joe Engal.

  • The mobile phone may be seen as a new technology in our day, but the idea was actually first conceived in the year 1908.
  • This statement is only true because the mobile phone is actually a high-tech radio. In 1908 a man named Nathan B. Stubblefield who lived in Murray, Kentucky applied for the U.S. Patent 887,357 for a wireless telephone; he originally applied his patent to only radio telephones.
  • Martin Cooper did not make the first working mobile phone, he made the first portable mobile phone.

  • James Russell invented the compact disc in 1965. James Russell was granted a total of 22 patents for various elements of his compact disc system. However, the compact disk did not become popular until it was mass manufactured by Philips in 1980.             The first working prototype was produced in 1979. At the time of the technology's introduction it had more capacity than computer hard drives common at the time. The reverse is now true, with hard drives far exceeding the capacity of CDs.
  • n 1979, Philips and Sony got together to manufacture the compact disc.
  • The team leaders of this project were Kees Immink and Toshitada Doi. Philps handled the manufacturing process along with the Eight-to-Fourteen Modulation (EFM), while Sony too care of the error connection method, better known as CIRC. However, Philips claims that this invention was not a one man's job but a collective contribution by members of both the companies who worked together as a team.

  • Audio CDs and audio CD players have been commercially available since October 1982.            Mass adoption didn't happen immediately -- CDs wouldn't overtake cassette tapes until the late 1980s. The first album to sell 1 million copies in the CD format and outsell its vinyl version was Dire Straits' "Brothers in Arms," released in 1985.
  • This disc was taken over by nearly all markets across the globe, especially the Europe and the United States consumer market. The first successful CD to be launched was Brothers in Arms in 1985.A compact disc (CD) is a popular form of digital storage media used for computer files, pictures, and music. The plastic platter is read and written to by a laser in a CD drive. It comes in several varieties including CD-ROM, CD-R, and CD-RW.  As with most new technologies, one reason for the slow spread of CDs was their steep price tags. The Sony CDP-101 player sold for the equivalent of $730 when it first hit Japanese shelves in 1982. Accounting for inflation, that's about $1,750 today. The audio CDs themselves were $15, which is $35 in 2012 dollars.
  • Standard CDs have a diameter of 120 millimeters (4.7 in) and can hold up to 80 minutes of uncompressed audio or 700 MB (actually about 703 MB or 737 MB) of data. The Mini CD has various diameters ranging from 60 to 80 millimeters (2.4 to 3.1 in); they are sometimes used for CD singles, storing up to 24 minutes of audio or delivering device drivers.
