Hieronim Derdowski, Kashubian-Polish intellectual and activist, was born to Kashubian parents in the Pomeranian village of Wiele. By the time Derdowski emigrated to the United States in 1885, he had already studied for the Roman Catholic priesthood, been repeatedly incarcerated by the German authorities, and edited a newspaper in the city of Torun. At the time, however, Derdowski was better known as a poet. Within two years of reaching the United States he became editor of the Winona, Minnesota Polish-language newspaper Wiarus. In this role he gained a reputation as a strong voice for the Polish-American community, also known as Polonia.

The Kashubians, also known as Cassubians or Kashubs, are a Lechitic ethnic group native to the historical region of Pomerania, including its eastern part called Pomerelia, in north-central Poland. Their settlement area is referred to as Kashubia. They speak the Kashubian language, which is classified as a separate language closely related to Polish.
