By 10:29 a.m., the lawns and courtyards stood empty, blanketed by silence.

On the morning of Sept. 11, 2001, Yale secretary Linda Lorimer was aboard a plane thousands of feet above New York City, headed for Texas.

On the morning of Sept. 11, 2001, Brian Kim ’04 left his room for class.

On the morning of Sept. 11, 2001, Metro-North trains ferried commuters from Union Station to Grand Central Terminal as they did every day.

On the morning of Sept. 11, 2001, history professor John Gaddis was preparing to lecture to his Cold War class of more than 400.

By 10:29 a.m., Gaddis had something new — something far more important — to say. “Focus on the things that have not changed: faith in your family, your friends, your country,” Gaddis told the crowd in the Art Gallery auditorium the next day. “What happened yesterday, Sept. 11, 2001, is going to be for your generation what Dec. 7, 1941 was for your grandparents’ generation. What Nov. 22, 1963 was for my generation. It is a defining moment.”

On the morning of Sept. 11, 2001, nine Yale graduates woke up early and went to the World Trade Center. That morning, they probably straightened their ties, packed their lunches and kissed their children. They went downtown for breakfast, for meetings, for work.

By 10:29 a.m. on Sept. 11, 2001, their lives were likely over.
