This year marks the 150th anniversary of one of the most influential children's books of all time, Lewis Carroll's Alice's Adventures in Wonderland. The book has inspired numerous films, plays and songs, and gave rise to an industry of children's toys. Illinois State University English Professor Jan Susina recently returned from England's Cambridge University where he lectured on the enduring legacy of Alice and her memorable companions, the White Rabbit, the Mad Hatter and Cheshire Cat.
