Jan Brzoza, real name Józef Worobiec or Józef Wyrobiec (10 December 1900 – 17 November 1971) was a Polish writer, publicist, radio-host, Communist activist and one of the founders of the proletarian literature in Poland.
Józef Worobiec was born in a Ukrainian working-class family (father Antoni and mother Katarzyna or Aniela).
He made his debut in 1932 with the novel Diaries of the unemployed (in Polish: Pamiętnikiem bezrobotnego), unexpectedly winning a special award established for unemployed youth by the Institute of Social Economy (IGS – Instytut Gospodarstwa Społecznego) at the peak of the economic crisis.
The other novel Building an edifice (Budowali gmach) about construction site workers and their strike was issued in 1938.
In 1944–1945, Brzoza was the editor of the Lviv newspaper Czerwony Sztandar (Red Banner).
