She is actually incredibly difficult to book – You have to reach out to her bookers at the Jane Goodall Institute: http://www.janegoodall.org
She travels most of the year, and I was told her schedule can fill up 8 months in advance. She gets more requests that she can accomodate so she turns down a fair amount of invitations. I put in a request last year and was turned down…it might help if you have some personal connections of if someone in your school’s anthropology department has a specific reason to reach out to her. She’s a fascinating woman and a great speaker though- Good luck!
