Joseph Alexander (also Johann; 1771 or 1772, Paderborn — June 6, 1840, Cologne) was a cellist active in Duisburg, Germany, noted for his teaching and pedagogical works.
He was distinguished more for the beauty of his tone and the excellence of his style than for any great command over technical difficulties.
He wrote an instruction book for his instrument, Anweisung für das Violoncell (Breitkopf und Härtel, 1801), that was popular enough to be reprinted in 1854.
He is also noted for his Air avec xxxvi Variations progressives pour le Violoncelle avec le doigté en différentes clefs, accomp.
His pupils included Johann Hermann Kufferath[2] and Jacques Offenbach.
