Along with Josif Pančić and Đura Daničić he belongs to the most prominent Serbs who have marked the spiritual rise and progress of Serbia in the second half of XIX century. For a number of years he was Rector of the Belgrade College, full member of the Serbian Learned Society, full member of the Serbian Royal Academy (its president from 1892 to 1895), corresponding member and president of State Council.

His great talent and enormous energy was aimed towards development of education in general, as well as to development of technical culture. He laid the foundations of contemporary university teaching of mathematics in Serbia. He was the author of the first textbooks in higher mathematics in Serbian language (three textbooks) and according to M. Milanković he considered it his primary task.
Being a pedagogue did not stop of involving himself in scientific work. He published eleven works in the Gazette of the Serbian Learned Societyand the Voice of the Serbian Royal Academy, mainly referring to mathematical analysis. He was our first mathematician that considered complexity of boundary processes', getting rid of formality of its application.
