Both Elvira and her guardian Friederich had died in 1866, and Suttner, now above the typical age of marriage, felt increasingly constrained by her mother's eccentricity and the family's poor financial circumstances. In 1873, she found employment as a tutor and companion to the four daughters of Karl von Suttner, aged between fifteen and twenty. The Suttner family lived in the Innere Stadt of Vienna three seasons of the year, and spent the summer at Schloss Harmannsdorf in Lower Austria. Suttner had an affectionate relationship with her four young students, who nicknamed her "Boulotte" due to her size, a name she would later adopt as a literary pseudonym in the form "B. Oulot". She soon fell in love with the girls' elder brother, Arthur Gundaccar, who was seven years her junior. They were engaged but unable to marry due to the Suttners' disapproval. In 1876, with the encouragement of her employers, Suttner answered a newspaper advertisement which led to her briefly becoming secretary and housekeeper to Alfred Nobel in Paris. In the few weeks of her employment Suttner and Nobel developed a friendship, and Nobel may have made romantic overtures. However, Suttner remained committed to Arthur and returned shortly to Vienna to marry him in secrecy, in the church of St. Aegyd in Gumpendorf.
