**The Little Schemer**, a book on recursive programming by Daniel P. Friedman and Matthias Felleisen

The Little Schemer (original title: The Little Lisper) is a book by Daniel P. Friedman and Matthias Felleisen, designed to introduce the principles of recursive programming to an audience who may have no prior experience of programming or mathematics. All the examples are in the Scheme language but it is not intended as an introduction to Scheme (although it is based on lecture notes from an "Introduction to Scheme" mini course) and only uses that subset of the language necessary to implement solutions to the various tasks set in the book.
