Tony Hsieh, the longtime ex-chief executive of Zappos, died on Friday after being injured in a house fire, his lawyer told the Las Vegas Review-Journal. He was 46.

The big picture: Hsieh was known for his unique approach to management, and following the 2008 recession his ongoing investment and efforts to revitalize the downtown Las Vegas area.

• After investing in Zappos in 1999 and running the online shoe seller, he sold the company to Amazon in 2009 for about $1.2 billion, where he stayed until stepping down in August.

Zappos has published a statement which reads, in part:

The world has lost a tremendous visionary and an incredible human being. We recognize that not only have we lost our inspiring former leader, but many of you have also lost a mentor and a friend. Tony played such an integral part in helping create the thriving Zappos business we have today, along with his passion for helping to support and drive our company culture.

Tony’s kindness and generosity touched the lives of everyone around him, as his mantra was of “Delivering Happiness” to others. His spirit will forever be a part of Zappos, and we will continue to honor his memory by dedicating ourselves to continuing the work he was so passionate about.
