As we are commemorating the 20th anniversary of 09/11, we asked French-American Director Jules Naudet who was the first person, together with a few firefighters, to enter Tower 1 at the World Trade Center, what he remembered from that very special day.

Jules and his brother Gedeon were filming a documentary on firefighters and happened to be near the Twin Towers by pure chance. The raw footage Jules was able to capture that day became a documentary in 2002. Fifteen years later, a new documentary New York 9/11 produced by CNN was released.

In this podcast, Jules Naudet remembers the sounds and smells of that day. He also talks about the influence of "his" 9/11 on the rest of his career.

He pays tributes to all firefighters and in particular New York City Fire Department Battalion Chief Joseph Pfeifer who saved his life, "a friend for life."

Jules Naudet is an alum from the Lycee Francais de New York.
