Later in life, Loewe became very popular both as a composer and as a singer. As a youth, he had a high soprano voice (he could sing the music of the Queen of the Night in "The Magic Flute" as a boy), and his voice developed into a fine tenor. He made several tours as a singer in the 1840s and 1850s, visiting England, France, Sweden and Norway amongst other countries. He eventually moved back to Germany, and, after quitting his posts in Stettin after 46 years, moved to Kiel, where he would die from a stroke on 20 April 1869.
