He died of apparent suicide on location for his show Parts Unknown. He was a really interesting character and his travelogue/food shows were entertaining. He started as a line cook in a restaurant, worked his way up to chef and through some fortunate circumstances (I don't remember the details) wound up writing a really popular book called Kitchen Confidential about what goes on behind the service counter. He kicked a heroine habit and dealt with depression on and off throughout his life. He was a great guy and will be missed.
