Ubiquitin, the Chazon Ish died at the beginning 5714. That is definitely two generations.
Joseph, the Netziv closed the yeshiva because the government, at the instigation of the Maskilim’ wanted to eevntually eliminate Torah learning altogether. On the other hand, talmidim in Pressburg took the external exams for the equivalent of a HS academic diploma (in NYS the Regents, in Israel the bagrut) and received draft deferments as theological students. This eventually turned out to be good for the Orthodox in Hungary as their rav, Rav Koppel Weiss, spoke to Franz Yosef in his native German whereas the head of the Neolog spoke in literary Hungarian, which is an extremely difficult language that gave the emperor fits. BTW, many American yeshivot as well as yeshivot for English speakers in Israel offer bachelors’ degrees in Talmudic Literature in conjunction with colleges. This enables the talmidim to go on for JDs or MBAs after earning high enough frades on the LSAT/GRE.
