R.I.P. -- Steve "The Crocodile Hunter" Irwin: 1962 - 2006
He was famous for his love of wildlife, his passion for the environment, and his infectiously over-the-top enthusiasm for pushing the envelope of fortune in pretty much anything he did. He represented Australia to the world like a true ambassador.
Sadly, on September 4, he was killed by a freak stingray barb that punched through his chest and hit him square in the heart.
Here's a Wikipedia article with the details.
UPDATE: The town of St. George in Queensland, where Steve owned some retreat and conservation property, is planning a memorial.
