In a statement on Tuesday, Goodall congratulated Project Chimps and New Iberia on their agreement, which she called an "historic achievement for chimpanzees."
"I am 100 percent in support, and am so glad this dream is coming true," she said.
Goodall isn't the only well-known figure to pledge her support to the chimps. A number of other celebrities have also been involved, including Green Day's Billie Joe Armstrong, actress Judy Greer, singer Pink, celebrity cook Rachael Ray (who sponsored the sanctuary's kitchen), tattoo artist Kat Von D and tennis star Serena Williams.
But for Baeckler Davis, the most important thing is that these chimps will finally have somewhere to retire in peace.
"It's the project of a lifetime for all of us," she said. "I definitely get teary when I allow myself to think about its magnitude."
Project Chimps will eventually host private educational tours - and there will be webcams for people who can't visit in person. If you'd like to help bring these chimps home, you can make a donation here.
