Adolf Jensen (12 January 1837 – 23 January 1879) was a German pianist, composer and music teacher.Jensen was born in Königsberg to a family of musicians. Although largely self-taught, he also had instruction from Louis Ehlert, Louis Köhler and Friedrich Marpurg (1825–1884). Marpurg was the director of the Königsberg Theater and the great-grandson of the music theorist Friedrich Wilhelm Marpurg. In 1856, Jensen went to Russia to teach in the hope of earning enough money to take lessons with Robert Schumann with whom he had been in correspondence.
