In truly sad and shocking news, former Zappos CEO and serial internet entrepreneur Tony Hsieh has passed away at age 46. Earlier this evening it was confirmed that Hsieh passed away peacefully surrounded by family members.

Hsieh’s motto was “Delivering Happiness” which he instilled into Zappo’s culture and used as the title of a book that he published in 2010 shortly after selling Zappos to Amazon for $1.2Billion. Tony is credited with helping revitalize Downtown Las Vegas along with numerous other philanthropic projects that served Zappos’ hometown of Las Vegas.

Details of Tony’s death have not been made public by his family.

Rest in peace, Tony.
