Since the end of the ferries the SED tried to enforce a rapid turnover
of the teaching staff of the East German universities. The professsor
iate in academic fields like economics or law could be changed complet
ely within a few years and in the humanities a small counter-elite of
former emigrants successfully started to build up a new teaching staff
. Only in the medical and natural sciences the old personnel, milieu a
nd mentality survived until the early sixties. Continuity in these dis
ciplines depended upon the lack of qualified scientists, the open bord
er in the West (until 1961), the autonomy of the scientific discourse
and the informal power of the academic establishment. In the social sc
iences and the humanities a rapid change was possible because the SED
was either able to implement an alternate elite of loyal intellectuals
or to destroy the scientific autonomy of these disciplines so that ac
ademic credentials where not an absolute prerequisite of the career fu
rther more.
