Description:
In this paper 21 dissertations for the doctor degree (chemistry) of the University of Sofia are listed and commented. They were defended in the period 1930-1943. The procedure of defending a thesis in this period is described. A concise history of the introduction of the PhD-system in the world universities is given. The comparison seems to be favorable for the system developed in the University of Sofia at that time.
