This annual lecture is held in support of Save the Rhino International and the Dian Fossey Gorilla Fund. Douglas was a Patron to both charities of course.
Nicky Springthorpe, the Fundraising and Communications Manager for Save The Rhino, tells me that the 2005 lecture will be given by Mark Carwardine, so "they're all very excited about that".
Please visit their Lectures And Talks page for more information on the 2005 lecture.
In celebration of the Life and Universe of Douglas Adams, late Founder Patron of Save the Rhino International. We host a lecture each year on (or as near as possible to) the day of Douglas's birthday to commemorate him and his achievements, on subjects that were of interest to him.
They also have a selection of Douglas Adams Books For Sale.
