author
1830–1889
A Belgian man of letters who moved between journalism, translation, theater, and fiction, leaving behind a small but varied body of 19th-century work. He is best remembered today for dark, dramatic writing such as Les fantômes, étude cruelle and for the socially charged Les Coulisses de l’anarchie.

by Ch. (Charles) Flor O'Squarr
Born in Brussels on March 22, 1830, Charles Flor O'Squarr was a Belgian writer, journalist, and translator who wrote in French. Reference records and literary databases identify him as an active 19th-century author, and surviving catalog entries show that his work ranged across several forms rather than fitting neatly into a single genre.
His known writings include the novel Les fantômes, étude cruelle, while bibliographic sources also connect him to the play Les pistolets de mon père, performed in Paris in 1870. He is also associated with Les Coulisses de l’anarchie, a work that helped preserve his name for later readers interested in politics, reportage, and the literary culture of the fin de siècle.
Some sources give his death year as 1890, while the library label you provided lists 1889, so the exact dating is not fully consistent across records. What does come through clearly is the picture of a versatile literary figure whose career touched journalism, translation, stage writing, and fiction at a time when those worlds often overlapped.
