Earliest real refs I have are in the 1965 TI and 1966 Fairchild catalogs, both

They both list JK types in the early RTL families, amongst others.
I presume the JK type was introduced as a common building block after the
development of ICs, as it's a relatively expensive construct, applications can
generally be implemented more optimally when using discrete components.
I find the Wiki entry, or it's phrasing, rather weak. The date mentioned (1968)
is a date of a letter about the origins of the name and it doesn't say anything
about the date of those origins. It's also ambiguous in saying Hughes used only
one type of FF and then implies there were 5 types.

Well, why not have someone add it to the Wikipedia page? Personally,
I tend to lean toward the first theory, as eponymically-designated
logic elements seems to fly in the face of established convention.
We don't talk aboiut Sheffer or Pierce gates, after all.
Or Jack Klugman.
More to the point, who's got documentary (instead of anecdotal)
proof? And was this truly the first implementation of this type of
flip-flop, or merely the first incidence that was specifically
documented and named?
