Tightroper Philippe Petit

Living legend Philippe Petit, famous for his dangerously high tightrope walking, particularly between the Twin Tower in 1974, celebrated his book Why Know? How to Tie More Than 60 Ingenious, Useful, Beautiful, Lifesaving and Secure Knots! with a party at the Cathedral Church of St. John the Divine in Morningside Heights. A lesser known fact is that Petit has held the title of artist in residence at the Church since 1980, when he took a trip across the 601-foot-long nave.
Petit’s newest book explains the knots he uses while up in the air, with detailed descriptions of how to tie and untie them. And rightly so – Petit won’t even take the first step on a wire unless he has checked the knots two or three times.
