    GO OBAMA FOR 2012, HE'S GOT A GREAT CHANCE OF WINNING, WHOOHOO!

  • Henry Sampson didn't invent the cell phone.

    The truly sad thing about this, is that you can find this bit of bullshit on Philadelphia public school website.

    Henry Sampson held a patent on an electric cell which had/has nothing to do with cellular phones.

    DO these Afrocentrists honestly believe that pumping this bullshit helps raise the self esteem of black people?

  • @Gulfporter u must think so oterwise u would not b here doing ur job, trying to bash black ppl. lol white ppl are funny if u want to find them just go look on a video about the gr8 things black ppl have done. they look in awe then they write something racist becasue they mad.

  • Alexander Twining in the USA and James Harrison in Australia used mechanical refrigeration to produce ice on a commercial scale. Around the same time, the Carré brothers of France led the development of absorption refrigeration systems. A more detailed timeline

  • Oliver Evans proposed a mechanical refrigerator based on a vapor-compression cycle in 1805 and Jacob Perkins had a working machine built in 1834. Dr. John Gorrie created an air-cycle refrigeration system in about 1844, which he installed in a Florida hospital.

  • Bernard Fantus, influenced by the Russian program, established the first hospital blood bank in the United States at Chicago's Cook County Hospital in 1937. It was Fantus who coined the term "blood bank." See highlights of transfusion history from the American Association of Blood Banks.

  • During World War I, Dr. Oswald H. Robertson of the US army preserved blood in a citrate-glucose solution and stored it in cooled containers for later transfusion. This was the first use of "banked" blood. By the mid-1930s the Russians had set up a national network of facilities for the collection, typing, and storage of blood.

  • The father of the cell phone is Martin Cooper who first demonstrated the technology in 1973

  • On July 6, 1971, Sampson and co-inventor George Miley received a patent on a "gamma electric cell" that converted a gamma ray input into an electrical output (Among the first to do that was Bernhard Gross, US patent #3122640, 1964). What, you ask, does gamma radiation have to do with cellular communications technology? The answer: nothing. Some multiculturalist pseudo-historian must have seen the words "electric" and "cell" and thought "cell phone."

  • lets try to keep it positive fella... after all slavery was abolished how long ago?

  • what song did you use for this? its awsome

  • Sam Cooke- A change gone come

  • These are great inventors of our culture, that have designed so many things and I am so blessed to be inspired.

    Brother Lewis Latimer, Brother Andrew Beard, Brother George Washington Carver, Brother Garrett A. Morgan, Brother Granville T. Woods, Brother Jan Matzenger, Brother Augustus Jackson and Sister CJ Walker and we shouldn't forget them and forget each other.
