Gather the youth, and listen to Mr. Hamza Salifu, who is usually referred to as the Encyclopedia Africana. He was the host of "The Best of Little Known Black History Facts" - a show hosted on Radio Universe (Ghana) , and has interviewed most of the inventors featured on this site and inventors displayed in the International Black Inventions Museum (a travelling museum). Mr. Salifu will discuss Black inventors of the past and present, such as Dr. Patricia Bath, M.D., the inventor of the cataract Laserphacoprobe, which is the medical instrument to remove cataracts from the eye and Granville T. Woods (b. 1856) inventor of the synchronous multiplex railway telegraph, a device which enable moving trains to communicate with one another, helping to avoid possible accidents.
