Absolutely, Knorr & F. Franz created much control!!! Not to excuse Rutherford but . . Knorr and Franz could hide behind the "curtain" more, to create their seeming more mysterious in the minds of their followers. But now, with media and Internet, the GB are having to get more 'public.' Talks are more easily recorded and taped to be sent everywhere. This GB are stuck but playing it all they can, but are seeming to enjoy it.
Worst JW behaviors were started and enforced by these two. Their cohorts only went along with them (as well as the rest of the org)
'Official' Disfellowshipping started in the 50s. This "DF" thing gave them all power. (Although there were some individuals cases before, as Rutherford could/would ). From there, blood transfusions became DF offense (1961). Also, from there became the damn 2-witness rule, protecting child molestors. Families weren't suppose to associate with DF family then either (though some did anyway secretly, as many do even now).
In those times (60s), became strong influence for no college. (it lightened up for awhile (after Knorr & Fred died) and came back as strong as ever).
They enforced the common term, 'organization' to become "ORGANIZATION." - their god.
