Steel....Evidence discovered in 1978 showed that East Africans were making steel for more than 1,500 years: “Assistant Professor of Anthropology Peter Schmidt and Professor of Engineering Donald H. Avery have found as long as 2,000 years ago Africans living on the western shores of Lake Victoria had produced carbon steel in preheated forced draft furnaces, a method that was technologically more sophisticated than any developed in Europe until the mid-nineteenth century.”
