In July 1862 Riemann married Elise Koch, a friend of his sister. This marriage brightened the last years of his life. In the fall of 1862 he caught a serious cold and tuberculosis set in. Riemann spent his last years almost entirely in Italy. Thanks to a petition of Weber and Sartorius von Waltershausen, known for his work on Mt. Etna, he received government subsidies on three occasions for recuperation. He returned to Göttingen, but the climate was too severe for him, and he did not attempt to give lectures. Riemann's last trip to Italy coincided with the beginning of the Seven Weeks' War between Hannover and Prussia. He arrived in Italy on June 28, 1866, the day Hannover capitulated.
