Twenty-five years after the September 11 attacks, Frank Siller stood at the White House and renewed a promise born from personal loss: “We will never forget.”
Siller, chairman and CEO of Tunnel to Towers, spoke at an anniversary event in Washington marking a quarter-century since the 2001 terrorist attacks. He remembered his brother, firefighter Steven Siller, who was killed while responding to the South Tower of the World Trade Center.
His account placed one family’s grief within a national act of remembrance. It also raised a pressing question for a new generation: how should the country preserve the stories of those who answered the call that day?
A moment that changed one family
Frank Siller recalled realizing that his brother was missing after the attack. That moment began a long period of grief, but it also led the family to make a lasting commitment.
“We will never forget.”
The short pledge has guided the family’s public remembrance of Steven. It also reflects the wider effort to honor firefighters, police officers, emergency workers and civilians killed during the attacks.
Steven Siller was among the first responders who went to the World Trade Center as danger grew in Lower Manhattan. He died while responding to the South Tower, one of two towers struck by hijacked planes.
For his family, the anniversary is not only a historic date. It is a reminder of a brother whose final actions were defined by service.
The meaning of 25 years
The September 11 attacks killed nearly 3,000 people in New York, at the Pentagon and near Shanksville, Pennsylvania. The attacks reshaped national security, foreign policy and daily life across the United States.
A 25th anniversary carries added weight because more Americans now have no direct memory of the day. People born after the attacks have reached adulthood, while those who witnessed them are passing their accounts to younger generations.
That shift makes personal testimony central to public education. Family stories can explain the human cost in ways that timelines and statistics cannot.
- The anniversary marks 25 years since the 2001 attacks.
- Steven Siller was killed while responding to the South Tower.
- Frank Siller now leads Tunnel to Towers as chairman and CEO.
- The family’s message centers on memory, sacrifice and service.
From private grief to public service
Tunnel to Towers carries forward Steven Siller’s memory through its work. Frank Siller’s leadership has made the firefighter’s story part of a broader mission tied to first responders, military families and Americans affected by catastrophic loss.
The White House setting gave that mission national visibility. Presidents and public officials have long used September 11 commemorations to honor victims while stressing unity and resilience.
Yet anniversary events also face a difficult task. They must respect private grief without turning individual lives into symbols alone. Frank Siller’s remarks kept the focus on one brother and one family’s realization that he would not return home.
That personal focus offered a clear message. National memory is sustained through names, relationships and firsthand accounts, not only through ceremonies.
Keeping the promise alive
The 25-year milestone arrives as institutions consider how September 11 should be taught and remembered in the decades ahead. Museums, schools, memorials and family organizations will play a larger role as firsthand memories grow less common.
Frank Siller’s words suggest that remembrance must remain active. It can include telling victims’ stories, supporting those who serve and helping younger people understand the choices made during the emergency.
The White House commemoration honored a national tragedy, but its emotional center was deeply personal. Steven Siller was a firefighter, a first responder and a brother who never came home.
A quarter-century later, his family’s promise remains unchanged. The next test is whether the country can carry that promise forward after the generation that witnessed September 11 is gone.
