In 1979, in the classroom at the right side of the entrance, the Museum of Vojvodina in Novi Sad has set an exhibition dedicated to life and work of Mihajlo Pupin, which stands to the present day. It unravels the life story of the great scientist, starting with the first steps he had taken in his parents' home to the immense success he achieved in the US and in his homeland.
