Jacob James Kwast was born in Nijkerk, Netherlands, in 1852. After studies with his father and Ferdinand Böhme in his home country, he became a student of Carl Reinecke at the Leipzig Conservatory, and had later studies in Berlin under Theodor Kullak, and Brussels under Louis Brassin and François-Auguste Gevaert. He settled in Germany in 1883, initially as a teacher at the Cologne Conservatory, and later at the Hoch Conservatory in Frankfurt and the Klindworth-Scharwenka (1903–06) and Stern conservatories in Berlin.
Clara Schumann played her last public concert in Frankfurt on 12 March 1891. The last work she played was Brahms's Variations on a Theme by Haydn, in the piano-duet version, with Kwast as her partner.
He died in Berlin in 1927, aged 74.
His reputation as a teacher reached far and wide. The list of his students includes:
- Hans Pfitzner (his future son-in-law)
- Carl Friedberg
- Percy Grainger
- Ethel Leginska
- Walter Braunfels (whom he introduced to the music of Pfitzner)
- Otto Klemperer (who studied under Kwast at three institutions and credited him with the whole basis of his music development)
- Ilse Fromm-Michaels
- Walter Burle Marx, and
- Edith Weiss-Mann.
- Hermann Zilcher
He later married a pupil of his, Frida Hodapp (13 August 1880 - 14 September 1949). She was also a pupil of Ferruccio Busoni, the soloist in the first performance of Busoni's Concertino, and the dedicatee of Max Reger's F minor Concerto, which she premiered in 1910. She also premiered Reger's Variations and Fugue on a Theme of Telemann, Op. 134, on 14 March 1915 at the Leipzig Gewandhaus. The work was dedicated to her husband.
His brother was the conductor Jan Albert Kwast (Quast).
