Nedeljko Koshanin (Čečina / Vionica, near Ivanjica, Principality of Serbia, 13 October 1874 - Graz, Austria, 22 March 1934) was a scientist biologist, university professor and academic at the Serbian Royal Academy, now the Serbian Academy of Sciences and Arts.
He was born on a farm in the village of Čečina, and according to some sources in the neighbouring Vionica near Ivanjica[2][verification needed] to parents Stana and Stevan.
[3] His parents enrolled him in an elementary school in Pridvorica, ten kilometres away from home, which he completed in 1887.
[6] At the end of 1899, however, he managed to join the civil service and for a short time worked as a professor-trainee[5]and a substitute teacher at the Second Belgrade Gymnasium.
[2][verification needed] Since he no longer had the conditions in Belgrade to continue his research in the field of physiology, because it required a well-equipped laboratory, he devoted himself to natural history.
[8] As early as 1898, as a student with Zoology professor Živojin Đorđević in Belgrade, he studied the insects of the Coleoptera in Serbia.
