Johann Carl Gottfried Loewe (30 November 1796 – 20 April 1869), was a German composer, tenor singer and conductor. In his lifetime, his songs were well enough known for some to call him the "Schubert of North Germany", and Hugo Wolf came to admire his work. He is less known today, but his ballads and songs, which number over 400, are occasionally performed. http://www.bach-cantatas.com/Lib/Loewe-Carl.htm

Friedrich Karl Kühmstedt (20 December 1809 – 8 January 1858).
