paragraph_text: The Immortal Beloved
  
  While Beethoven was at Teplitz in 1812, he wrote a ten-page love letter to his " Immortal Beloved ", which he never sent to its addressee. The identity of the intended recipient was long a subject of debate, although the musicologist Maynard Solomon has argued that the intended recipient was Antonie Brentano; other candidates included Julie Guicciardi, Therese Malfatti and Josephine Brunsvik.
  
  All of these had been regarded by Beethoven as possible soulmates during his first decade in Vienna. Guicciardi, although she flirted with Beethoven, never had any serious interest in him and married Wenzel Robert von Gallenberg in November 1803. (Beethoven insisted to his later secretary and biographer, Anton Schindler, that Guicciardi had "sought me out, crying, but I scorned her".) Josephine had, since Beethoven's initial infatuation with her, married the elderly Count Joseph Deym, who died in 1804. Beethoven began to visit her and commenced a passionate correspondence. Initially, he accepted that Josephine could not love him, but he continued to address himself to her even after she had moved to Budapest, finally demonstrating that he had got the message in his last letter to her of 1807: "I thank you for wishing still to appear as if I were not altogether banished from your memory". Malfatti was the niece of Beethoven's doctor, and he had proposed to her in 1810. He was 40, and she was 19. The proposal was rejected. She is now remembered as the possible recipient of the piano bagatelle known as Für Elise.
  
  Antonie (Toni) Brentano (née von Birkenstock), ten years younger than Beethoven, was the wife of Franz Brentano, the half-brother of Bettina Brentano, who provided Beethoven's introduction to the family. It would seem that Antonie and Beethoven had an affair during 1811–1812. Antonie left Vienna with her husband in late 1812 and never met with (or apparently corresponded with) Beethoven again, although in her later years, she wrote and spoke fondly of him. Some speculate that Beethoven was the father of Antonie's son Karl Josef, though the two never met.
  
  After 1812 there are no reports of any romantic liaisons of Beethoven's; however, it is clear from his correspondence of the period and, later, from the conversation books, that he occasionally had sex with prostitutes.
