Firefighter Robert "Bobby" Dismas McMahon (b. 1965) was killed at the World Trade Center during fire and rescue operations following the terrorist attacks of September 11, 2001. He was a member of Ladder Company 20 on Lafayette Street, and with his wife Julie, bought and renovated the house he grew up in in Woodside, Queens.

Twenty-five years later, we honor the Queens residents, first responders, workers, and volunteers who lost their lives on September 11, 2001, or died from 9/11-related illnesses. Each lived in or shared a deep connection with Queens, and many are remembered through local memorial sites and co-named streets featured here on the Queens Name Explorer. On this page, we remember those lost from the following neighborhoods: Astoria, Hunters Point, Long Island City, Maspeth, Steinway, Sunnyside and Woodside.
