ctorandus', the Latin term implying that he or she is now qualified to
pursue further studies that will eventually lead to a doctorate. The
Dutch system of an academic career leading to a PhD-type doctorate is
explained and compared with the German system, leading to a 'Habilitat
ion'. The author recounts how a long research fellowship at Erasmus Un
iversity Rotterdam eventually resulted in the successful defence of hi
s thesis 'The early human fetal ductus arteriosus' and the award of a
doctorate from that institution.
