Joop, who is also referred to as "experimental subject 626," was originally "harvested by British explorers in the early 1900s." On September 21, 2005, Joop celebrated his 105th birthday, which was called a milestone in the Life Extension Project by the Hanso Foundation. The Hanso Foundation website featured a section called "Joop's Corner", where users could find information about the orangutan, watch him on a webcam, and even write him messages. Pictures of Joop going wild could be seen after logging out of the thehansofoundation.org website.
