Lubicz-Niezabitowski was born in Bugaj near Miłosław to Hieronim Michał and Władysława Ogończyk née Dąbrowska.
During his student days he assisted Władysław Kulczyński and Konstanty Jelski organize specimens in the museum.
Here he set up a medical practice as well and in his spare time collected specimens from around the region including summer holidays at Montemaggiore in Istria.
He also collaborated with Marian Łomnicki on the Staruń excavations and spent some time at the marine biology station in Naples.
He joined the faculty of medicine at the Jagiellonian University in 1920 on an invitation from Heliodor Święcicki (1854-1923) but there was some confusion in the posting which clashed with that of Jan Kazimierz Wilczyński.
