In this paper we present digitized works of Dragomir Simeunović (1930-2021), a former professor of mathematics at Belgrade University. We consider that his works should be interesting to the wider audience for two reasons. The first one is that he initially finished astronomy and was one of the last students of the famous Serbian astronomer and applied mathematician Milutin Milanković. Secondly, he also graduated in mathematics and after that his scientific work was completely devoted to geometry of polynomials, a discipline founded in Serbia by Mihailo Petrović Alas, the father of modern mathematics in Serbia. Digital copies of Simeunović’s works are deposited in the Virtual Library of the Faculty of mathematics, elibrary.matf.bg.ac.rs.
