Stephen Robert "Steve" Irwin (22 February 1962 – 4 September 2006), nicknamed "The Crocodile Hunter", was an Australian wildlife expert, television personality, and conservationist. Irwin achieved worldwide fame from the television series The Crocodile Hunter, an internationally broadcast wildlife documentary series which he co-hosted with his wife Terri. Together, the couple also owned and operated Australia Zoo, founded by Irwin's parents in Beerwah, about 80 kilometres (50 mi) north of the Queensland state capital city of Brisbane. Irwin died on 4 September 2006 after being pierced in the chest by a stingray barb while filming an underwater documentary film titled Ocean's Deadliest. The Sea Shepherd Conservation Society ship MY Steve Irwin was named in his honour.
In 1991, Irwin met Terri Raines, an American naturalist from Eugene, Oregon who was visiting wildlife rehabilitation facilities in Australia and had decided to visit the zoo. According to the couple, it was love at first sight. Terri said at the time, "I thought there was no one like this anywhere in the world. He sounded like an environmental Tarzan, a larger-than-life superhero guy." They were engaged four months later and were married in Eugene on 4 June 1992. Together they had two children: a daughter, Bindi Sue Irwin (born 24 July 1998), and a son, Robert Clarence "Bob" (named after Irwin's father) Irwin (born 1 December 2003). Bindi Sue is jointly named after two of Steve Irwin's favourite animals: Bindi, a saltwater crocodile, and Sui, a Staffordshire Bull Terrier who died on 23 June 2004. Irwin was as enthusiastic about his family as he was about his work. He once described his daughter Bindi as "the reason [he] was put on the Earth." His wife once said, "The only thing that could ever keep him away from the animals he loves are the people he loves even more." Although the Irwins were happily married, they did not wear wedding rings; they believed that in their line of work, wearing jewellery could pose a hazard to them and/or the animals.
