I don't know what Jack was using, but probably APL/360, as it dates from
a couple years before that. Things moved fast in those days. But there
was a non-IBM implementation of APL for the 7090 at Stanford in 1965,
I can tell you with certainty that APL was big business - outside of IBM
- as early as one year later than Jack's date. And that non-IBM
implementations were commercial in 1970.
I started programming in APL in the summer of (I think) 1973.

There are plenty of more credible places on the web to get that kind of
information. It will sometimes nerequire more than a single click.
 However, it only took me 2 minutes just now to learn about the 7090
APL (and a lot of other APL timeline).
If you are trying to research computer history, or most really most
anything, a better question to generally ask might be:
"Could the Wikipedia article be right?"
I thought that even junior high school students are taught that
Wikipedia is not a credible reference, and is unsuitable for citation in
homework. Wikipedia can be a starting point for extra hints about
looking for real information, if you have absolutely no idea what you're
looking for and are totally clueless, and can't muster enough Google-fu
to type in things like "APL timeline".
Sometimes Wikipedia has correct information, if it's something they just
copied out of a textbook on a purely factual matter. Like math and
physics. I use it all the time!
