On Sept. 11, 2001, seven members of Ladder Company 20 on Lafayette Street in the NoLIta neighborhood of Manhattan were killed in the collapse of the World Trade Center, about a mile and a half away, along with seven members of Squad 18, which shared the firehouse at the time with the ladder company.
A few weeks later, during the period of mourning that followed, a purebred Dalmatian puppy showed up at the company’s doorstep.
The dog, a gift from two deputies with the Monroe County sheriff’s department in upstate New York, was given the name Twenty, after the ladder company.
