Having realised he could make a living as a writer, Hesse finally married Maria Bernoulli (of the famous family of mathematicians) in 1904, while her father, who disapproved of their relationship, was away for the weekend. The couple settled down in Gaienhofen on Lake Constance, and began a family, eventually having three sons. In Gaienhofen, he wrote his second novel, "Beneath the Wheel", which was published in 1906. In the following time, he composed primarily short stories and poems. His story "The Wolf", written in 1906–07, was "quite possibly" a foreshadowing of "Steppenwolf".
