During 30 years, the professor of pharmacy Georg Dragendorff (1836-1898), who had been invited from Germany, supervised 90 theses of Master of Pharmacy and 87 theses of Doctor of Medicine in Tartu/Dorpat. The present article discusses the authors of these theses, Dragendorff and his co-operation with other university lecturers, the structure of the theses and the regulations of the thesis defence. Analysis of the contents of the theses revealed extensive contacts of the pharmacy of the time with different fields of science. Dragendorff as the supervisor of these theses contributed much to the training of physicians.
