Also, his research and studies of the detailed chemistry, mineralogy, and isotopic compositions of meteorites provide invaluable clues to the range of chemical and physical processing and timing of events in the solar nebula.
Janković was born in 1758 to a Serbian family in Neusatz Stadt (modern Novi Sad), then part of the Military Frontier of the Habsburg monarchy (now Serbia).
In 1790 he and Damjan Kaulić both independently petitioned for a Serbian printing house in Novi Sad, but were rejected by the Austrian government.
His importance lies in his pioneering work at the period of the Age of Enlightenment in such diverse fields as science, drama, and publishing, as well as in the use of the vernacular in literature.
Janković was a native of Novi Sad, Banat, and his critics regard him as a crude precursor of Vuk Karadžić, the famed reformer of the Serbian language.
