His father, György Nyisztor, was a farmer, and his mother, Anna Buga, was a servant.

He joined the labor movement at the beginning of the 1890s, where he encountered socialist ideas, and together with two of his friends, he founded the local organization of the Social Democratic Party of Hungary (Magyarországi Szociáldemokrata Párt or MSZDP) in Szatmárnémeti.

He was present at the social democratic meetings that prepared the revolutionary movement of October 1918.

After the fall of the Soviet Republic, he set himself the goal of further maintaining the Land Workers' Union, but was arrested on 5 August.

In 1921, he was transferred to the Soviet Union as part of the Soviet-Hungarian prisoner exchange, from where he returned home as a pensioner in 1945.
