Nik Wallenda

Nikolas "Nik" Wallenda (born January 24, 1979) is an American acrobat, aerialist, daredevil, and high wire artist. Described as "The King of the Wire", he is known for his high-wire performances without a safety net. He holds seven Guinness World Records for various acrobatic feats, but is best known as the first person to walk a tightrope stretched directly over Niagara Falls on June 15, 2012; the feat was broadcast internationally. The walk came after a two-year legal battle involving both sides of the Canada–United States border to gain approval. For the walk he was required to wear a safety harness for the first time in his life.
