Rumel, whose talent was often compared to the one of Krzysztof Kamil Baczyński, was born in Saint Petersburg during World War I, and grew up in Krzemieniec in the Wołyń Voivodeship province of the Second Polish Republic.

Rumel supported the idea of multinational Poland, and cooperated with a bilingual (Polish and Ukrainian) magazine Młoda Wies – Molode Selo, which was published in Krzemieniec.

In 1939, resulting from the joint invasion of Poland by Nazi Germany and Soviet Union, the province of Volhynia was incorporated into the Ukrainian SSR in the atmosphere of terror.

They failed to cross the border, and returned to Lutsk, where they were met by envoys of the Union of Armed Struggle (ZWZ), Tadeusz Majewski and Jerzy Potapow, who came to Volhynia to build the organization.

Zygmunt survived because he remained in Warsaw, where he married Anna (née Wojciszkiewicz), and together with another brother, Stanisław, ran a hardware store in the Ochota district.

According to Polish literary critic Bozena Gorska, Rumel's poetry was strongly influenced by the works of Juliusz Słowacki and Cyprian Kamil Norwid.

He rarely drew inspiration from the works of Polish avant-garde poets, but in some of his poems influences of Leopold Staff and Boleslaw Lesmian can be found.

In 2004, Polish film director Wincenty Ronisz produced a documentary Poeta nieznany (Unknown poet), which describes the life and death of Rumel.
