I would argue that functional programming predates functioning computers. Alonzo Church developed the [Lambda Calculus](https://en.wikipedia.org/wiki/Lambda_calculus) in the 1930s. This may be a fairly austere form of functional programming, but I think it qualifies. As noted in a comment, Lisp (which was heavily influenced by the lambda calculus) was developed in the 1950's; that's a long time before people started developing the idea of object orientation.
