Nizet developed an interest in Romania, perhaps due to the influence of émigrés and students who lodged with the family. Her first poetic works were published in 1878, written during the Romanian War of Independence and before the Congress of Berlin secured Romania's independence, expressed her support for the Romanians and her opposition to Russia's attempts to dominate Romania. Her early work met with some success but her literary career was to be short, ending in 1879 when she married.
