contain the Chorale Preludes with Schweitzer's analyses, were to be worked on in Africa, but these were never completed, perhaps because for him they were inseparable from his evolving theological thought. On departure for Lambaréné in 1913, he was presented with a pedal piano, a piano with pedal attachments to operate like an organ pedal-keyboard. Built especially for the tropics, it was delivered by river in a huge dug-out canoe to Lambaréné, packed in a zinc-lined case. At first, he regarded his new life as a renunciation of his art, and fell out of practice, but after some time he resolved to study and learn by heart the works of Bach, Mendelssohn, Widor, César Franck, and Max Reger systematically. It became his custom to play during the lunch hour and on Sunday afternoons. Schweitzer's pedal piano was still in use at Lambaréné in 1946. According to a visitor, Dr. Gaine Cannon, of Balsam Grove, N.C., the old, dilapidated piano-organ was still being played by Dr. Schweitzer in 1962, and stories told that "his fingers were still lively" on the old instrument at 88 years of age. Sir Donald Tovey dedicated his conjectural completion of Bach's The Art of Fugue to Schweitzer. Schweitzer's recordings of organ-music, and his innovative recording technique, are described below. One of his pupils was conductor and composer Hans Münch. Theology In 1899, Schweitzer became a deacon at the church of Saint Nicholas in Strasbourg. In 1900, with the completion of his licentiate in theology, he was ordained as curate, and that year he witnessed the Oberammergau Passion Play. In the following year he became provisional Principal of the Theological College of Saint Thomas, from which he had just graduated, and in 1903 his appointment was made permanent. In 1906, he published Geschichte der Leben-Jesu-Forschung [History of Life-of-Jesus research]. This book, which established his reputation, was first published in English in 1910 as The Quest of the Historical Jesus. Under this title the book became famous in the English-speaking world. A second German edition was published in 1913, containing theologically significant revisions and expansions: this revised edition did not appear in English until 2001. In 1931, he published Mystik des Apostels Paulus (The Mysticism of Paul the Apostle); a second edition was published in 1953. The Quest of the Historical Jesus (1906) In The Quest, Schweitzer criticised the liberal view put forward by liberal and romantic scholars
