For whomever submits stories like this, please say who the person was. Very few people are so famous that everyone in tech knows who they were, and Mr. Atkinson was not one of them. I've heard of his accomplishments, but never the man himself.
Atkinson was a brilliant engineer. As critical to the launch of A Macintosh as anyone — efficient rendering of regions, overlapping windows, etc.
And last but not least, Mac Paint. Every computer painting program in existence owes Atkinson a nod.
This gave rise both to the Science Citation Index and to various hypertext systems. For example the famous 1968 presentation https://www.youtube.com/watch?v=yJDv-zdhzMY, now known as "The Mother of All Demos", demonstrated a working hypertext system among the other jaw-dropping accomplishments.
HyperCard brought hypertext to commodity hardware. The Web made a distributed hypertext system viable. Google's PageRank recombined hypertext and the Science Citation Index to make the web more usable. And all of the key insights trace back to Vannevar Bush. Who was able to have such deep insights in 1945 because he had been working in, and thinking about, computing at least since 1927.
The history of important ideas in computing generally goes far deeper than most programmers are aware.

answer "HyperTalk!" with "OK"
end mouseDownHyperCard was really cool and I miss it. Its most important feature IMO was to enable non-programmers to rather easily author useful software. As happend with Excel.
The idea that information can be hyperlinked is much older than HyperCard. Check out Ted Nelson and his https://en.wikipedia.org/wiki/Project_Xanadu which predates HyperCard by more than a decade.
And then there was the https://en.wikipedia.org/wiki/Symbolics_Document_Examiner, or GNU Texinfo and its precursors besides many other attempts.
