> Lisp is about a year younger than Fortran, which makes it the second oldest language still in use today I disagree with this line since Lisp is not really a "language", but a family of them. If we consider Clojure and original Lisp to be the same language, we should also consider that to be true of Algol and Rust.

The original LISP was a language and its implementation. It was also documented - see for example the LISP 1 manual and other publications about it. From that a series of languages evolved, which shared the original core (syntax, data structures, operators, ...) That's what I would consider the core Lisp language family. Most of these languages will have 'Lisp' in its name.
