Knights of the Lambda Calculus
![The Knights of the Lambda Calculus' recursive emblem celebrates LISP's theoretical foundation, the lambda calculus. Y in the emblem refers to the fixed-point combinator and the reappearance of the picture in itself refers to recursion.](/Images/godic/202501/22/Knights_of_the_Lambda_Calculus.svg5759.png")
The Knights of the Lambda Calculus is a semi-fictional organization of expert LISP and Scheme hackers. The name refers to the lambda calculus, a mathematical formalism invented by Alonzo Church, with which LISP is intimately connected, and references the Knights Templar.
