Photos: Retired Zappos CEO Tony Hsieh dies from fire injuries

Tony Hsieh, the high-profile former CEO of online shoe retailer Zappos.com, has died at the age of 46.

The businessman - who amassed a fortune of $840 million - died Friday following injuries he sustained in a house fire in Connecticut, where he was visiting friends. The blaze broke out inside a waterfront mansion in the town of New London in the early hours of November 18, according to GeekWire. 

Neither Hsieh's lawyer or public relations manager have provided further details on the fire, and an official cause of death has not been announced. Hsieh, who was born in Illinois and was the son of Taiwanese immigrants, studied at Harvard University before he joined Zappos - then called ShoeSite.com - in 1999. As CEO, he helped transform the fledgling internet start-up into a billion-dollar business. 

Zappos was sold to Amazon for $1.2 billion in 2009, but Hsieh remained with the company until his retirement earlier this year. 

While Hsieh became known for his business acumen, it was his philanthropy and his focus on fostering a positive workplace culture for which he is now being remembered.
