Columbia Remembers: 25 Years After 9/11
Twenty-five years after September 11, 2001, we remember the nearly 3,000 people whose lives were taken that day, and we honor their families and loved ones, survivors, first responders, and all those whose lives were forever changed.
For New Yorkers, September 11th is inseparable from the memory of this city. Its impact lives in our families, neighborhoods, institutions, and communities. For many, the events of that day remain deeply personal; for younger generations, they are also encountered through the stories of parents and grandparents, photographs, memorials, classrooms, and the city itself.
Those different experiences exist alongside one another. They remind us that the memory of September 11th is made up of countless individual lives and perspectives—and that the ways communities remember are continually shaped by the people who carry those memories forward.
This idea resonates with the Alliance Program’s Vis à Vis episode “Can Memory Change the Present?”, featuring sociologist Sarah Gensberger of Sciences Po and Columbia University historian Carol Gluck. Their conversation explores collective and public memory, and how our understanding of the past is shaped by families, communities, institutions, relationships, and the societies in which we live.
Gensburger’s research also asks us to consider whose memories are preserved, whose stories are heard, and how social circumstances influence the ways people participate in remembrance.
Today, we remember those who were lost and those who carry their memory. We remember the people who cared for strangers, the communities that supported one another, and a city confronted with profound grief.
Twenty-five years later, New York continues to remember—publicly and privately, collectively and individually. And as those memories are carried forward, we continue to listen to one another.
We invite you to explore collective remembrance further, and listen to the episode, “Can Memory Change the Present?”
