He lived and worked subsequently in Basel, Paris, Cologne and The Hague to finally settle in Stuttgart, where he became director of the music conservatory.
De Lange befriended many fellow composers, including Johannes Brahms, Max Bruch and Max Reger, and dedicated compositions to Friedrich Grützmacher (1st cello concerto), Hugo Becker (2nd cello sonata), Charles-Marie Widor and Johannes Brahms.
For example Friedrich Hebbel's poem Ein frühes Liebesleben is used in an unusual instrumentation for voice, string quartet and harp.
An arrangement with piano instead of harp was made during a centennial revival of Samuel and Daniël de Lange's music.
De Lange is still "notorious" for his Tägliche Übungen im Pedalspiel, a practice book for playing the organ pedal keyboard.
