(b Königsberg [now Kaliningrad], 12 Jan. 1837; d Baden-Baden, 23 Jan. 1879). German composer. He worked as a piano teacher until ill health compelled him to retire to various south German and Austrian resorts. His early music—mainly songs and piano music—recalls Schumann, but he was later influenced by Liszt and Wagner. Some of his songs show his intention ‘to translate Wagner's ideas of beauty and truth into music in the smaller forms’, and reflect or even anticipate Tristanesque harmony. His brother Gustav Jensen (b Königsberg, 25 Dec. 1843; d Cologne, 26 Nov. 1895) was a violinist and composer who also made editions of old violin music.
