b. 1820
Remembered as a Polish nobleman and military figure from the 19th century, he is not well documented online as a literary author. The surviving public sources are sparse, which gives his story an air of mystery.

by Juliusz Rawicz Przyjemski
Publicly accessible sources found during this search identify Juliusz Rawicz Przyjemski mainly by name, but they do not provide a well-developed author biography or a clearly documented body of literary work.
Because the available information is so limited, it would be safer to describe him simply as a 19th-century Polish figure associated with the Rawicz-Przyjemski family, rather than make stronger claims about his life or writing. If you have a specific book title or source edition connected to him, that would make it much easier to build a fuller and more reliable author note.
