President John F. Kennedy, 36th president of the United States, visited Nashville, Tenn., May 18, 1963. At a Founder’s Day ceremony at Vanderbilt University, President Kennedy pressed a gold telegraph key that remotely exploded the first charge of dynamite at the U.S. Army Corps of Engineers Nashville District’s construction site of Cordell Hull Dam at Cumberland River mile 313.5 in Carthage, Tenn. This video, which has no audio, shows the president pressing the gold telegraph key and the explosion at the construction site. The U.S. Army Corps of Engineers Nashville District constructed Cordell Hull Dam and dedicated the dam Oct. 13, 1973. The district still operates and maintains the dam.
