Wright struggled with the loss of Borthwick, experiencing symptoms of conversion disorder: insomnia, weight loss, and temporary blindness. After a few months of recovery, aided by his sister Jane Porter, Wright moved to an apartment he rented in Chicago at 25 East Cedar Street. The attack also had a profound effect on Wright's design principles; biographer Robert Twombly writes that his Prairie School period ended after the loss of Borthwick. Taliesin II Within a few months of his recovery, Wright began work on rebuilding Taliesin, naming the rebuilt structure "Taliesin II": There is release from anguish in action. Anguish would not leave Taliesin until action for renewal began. Again, and at once, all that had been in motion before at the will of the architect was set in motion. Steadily, again, stone by stone, board by board, Taliesin the II began to rise from Taliesin the first. The new complex was mostly identical to the original building. The dam (which burst less than a week after the murders) was rebuilt; Wright added an observation platform, perhaps inspired by the one he designed in Baraboo. Later, he built a hydroelectric generator in an unsuccessful effort to make Taliesin completely self-sufficient. The generator was built in the style of a Japanese temple. Within only a few years, parts of the structure eroded away. It was demolished in the 1940s. Around Christmas time of 1914 while designing the residence after the first devastating fire, Wright received a sympathetic letter from "Maude" Miriam Noel, who contacted him after reading about the Taliesin fire and murders. Wright exchanged correspondence with the wealthy divorcee and met with her at his Chicago office. Wright was quickly infatuated, and the two began a relationship. By spring 1915, Taliesin II was completed and Noel moved there with Wright. Wright's first wife Catherine finally granted him a divorce in 1922, meaning that Wright could marry Noel a year later. Although Wright admired Noel's erratic personality at first, her behavior (later identified as schizophrenia) led to a miserable life together at Taliesin. Noel left Wright by the spring of 1924. In the new Taliesin, Wright worked to repair his tarnished reputation. Already in 1916, he had secured a commission to design the Imperial Hotel in Tokyo, Japan; when the building was undamaged following the Great Kantō earthquake of 1923, Wright's reputation was restored. Although he later expanded the agricultural wing, Wright
