Mathematica's notebooks were released with v1.0 in 1988 and are the earliest notebook implementation I'm aware of. Jupyter isn't directly related except that they were a spinoff of a project partially inspired by Mathematica, IPython.
I've been running Wolfram in my Jupyter environment lately, which is a nice setup to do quick analysis without the hell is Mathematica licensing.
