To honor Stephen, his loved ones host an annual charity event, the Tunnel to Towers Run. This 3.1 mile run retraces Stephen's footsteps on that fateful day. Some participants even wear firefighter gear while they run...just like Stephen did.
As the runners make their way through the Brooklyn-Battery Tunnel, they pass photos of fallen firefighters who, along with Stephen, courageously ran into the towers hoping to save lives.
Stephen's family has also raised funds for the Stephen Siller's "Let Us Do Good" Children's Foundation. The donations help provide housing for orphans, money for burn centers around America and scholarships for children who have lost a parent in the Iraqi war.
Today, Oprah invited 92 of his family and friends to the show, including his wife, Sarah, and their five children. She also invited hundreds of New York City firemen, policemen, Port Authority workers and rescue workers to be a part of the show.
"We thank you," Oprah says.
