The private Anthony Bourdain

When Anthony Bourdain, the chef, bestselling author and globetrotting TV star, died by suicide three years ago at the age of 61, the news stunned those closest to him.  New York City chef Gabrielle Hamilton was shattered: "I had to go home and lie down on the floor, I mean, actually for kind of weeks," she said.

Lydia Tenaglia, who produced his hit show "Parts Unknown," was mystified: "Why would someone who seemingly had the best job in the world, the most incredible life, why would he make a decision to, you know, check out?" His brother, Christopher Bourdain, struggled with so many other emotions.
