Mr Rudolf Marosy was born in Braşov, Transylvania, Austria-Hungary (in modern-day Romania) on 19 November 1882. Born into a Roman Catholic family, he was the son of Augustinus and Julianna Marosy.

Little is known about Marosy’s early life but by April 1912 he was serving as a fireman aboard the eastbound voyage of the Carpathia when that ship rescued the survivors of the Titanic disaster.

Marosy evidently did not remain at sea long after those events and in September 1912 set foot on American soil as an immigrant, having sailed aboard the vessel Laura. A late resident of Kolazsvár, Austria-Hungary (modern-day Cluj-Napoca, Romania), he made his home in Cleveland, Ohio where he worked as a labourer, becoming a US citizen in 1923. 

Rudolf Marosy suffered from heart disease in later years and died in Cleveland on 1 February 1946; he was buried three days later in Highland Park Cemetery.
