Functional programming has been around for a very long time. Many regard the advent of the language LISP, in 1958, as the starting point of functional programming. On the other hand, LISP was based on existing concepts, perhaps most importantly those defined by Alonzo Church in his lambda calculus during the 1930s and 1940s. That sounds highly mathematical, and it was — the ideas of mathematics were easy to model in LISP, which made it the obvious language of choice in the academic sector. LISP introduced many other concepts that are still important to programming languages today.
