Tony Hsieh

Hsieh was with family when he died Friday, according to DTP Companies, which he founded. He died of injuries suffered in a Nov. 18 fire in New London, Connecticut, Downtown Partnership spokesperson Megan Fazio told Hearst Connecticut Media on Saturday.

The Day newspaper reported the day of the fire that one person had been removed from a waterfront home in New London with possible burns and smoke inhalation. The person, whose name authorities did not release, was eventually taken to Bridgeport Hospital, which has a burn center.

For years, Hsieh also worked to revitalize downtown Las Vegas, pledging $350 million in 2013 for redevelopment. The same year he moved Zappos’ headquarters into the former Las Vegas City Hall building.

“Tony Hsieh played a pivotal role in helping transform Downtown Las Vegas,” Nevada Gov. Steve Sisolak tweeted Friday night. “Kathy and I send our love and condolences to Tony’s family and friends during this difficult time.”
