The scholarly merits of Zsigmond Simonyi, numerous as they were, were also enhanced by his activity in supporting students. One of his students was Jozsef Papay, whose manuscript posthuma have been preserved in the Library of the Calvinist College in Debrecen. Manuscript sources proving the fellowship of master and student are discussed in the present paper. In letters and diaries, there are plenty of interesting data confirming the role Simonyi had played in the fact that his student proposed an analysis of Reguly's Ostyak collection. Pal Gyulai and Zsigmond Simonyi recommended Papay to the third Zichy expedition. Simonyi also provided for the copying of Reguly's four heroics and transporting them to Siberia. He helped Papay in his efforts to find work and publish articles after returning home. The paper is concluded by an obituary of Simonyi that was also found among the Papay manuscripts.
