Python comes from Monty Python. C++ is the successor of C. C is the letter after B (another programming language). Haskell is named after Haskell Curry. Ada is inspired by Ada Lovelace. Java is coffee. Lisp is a contrived abbreviation of LISt Processor.
All of these facts can be found on the Wikipedia pages for the languages listed above, and more or less all other programming languages in existence have similar information linked to them—even ML, the MetaLanguage.
But not Julia.
