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. However, Schumann had died in the interim. In 1857, he became was the music director of the Posen municipal theatre. From 1858 until 1860, he lived in Copenhagen and befriended Niels Gade.

He taught advanced piano at Carl Tausig's Schule des höheren Clavierspiels in Berlin from 1866 until 1868 when serious illness forced him to retire. He went to Dresden, then to Graz in 1870, and finally to Baden-Baden where he died of tuberculosis at the age of 42.
