Title:
Nikola_Tesla

Context:
In December 1878, Tesla left Graz and severed all relations with his family to hide the fact that he dropped out of school. His friends thought that he had drowned in the Mur River. Tesla went to Maribor (now in Slovenia), where he worked as a draftsman for 60 florins a month. He spent his spare time playing cards with local men on the streets. In March 1879, Milutin Tesla went to Maribor to beg his son to return home, but Nikola refused. Nikola suffered a nervous breakdown at around the same time.
