Schweitzer’s first language was the Alsatian dialect of German. At the Mulhouse gymnasium he received his “Abitur” (the certificate at the end of secondary education) in 1893. He studied organ in Mulhouse from 1885 to 1893 with Eugène Munch, organist at the Protestant cathedral, who inspired Schweitzer with his enthusiasm for the music of German composer Richard Wagner. In 1893, he played for the French organist Charles-Marie Widor (at Saint-Sulpice, Paris), for whom Johann Sebastian Bach’s organ music contained a mystic sense of the eternal. Widor, deeply impressed, agreed to teach Schweitzer without fee, and a great and influential friendship thus began.

From 1893 Schweitzer studied Protestant theology at the Kaiser Wilhelm University in Strasbourg. There he also received instruction in piano and counterpoint from professor Gustav Jacobsthal, and associated closely with Ernest Munch, the brother of his former teacher, organist of St William church, who was also a passionate admirer of J.S. Bach’s music. Schweitzer served his one-year compulsory military service in 1894. Schweitzer saw many operas of Richard Wagner in Strasbourg (under Otto Lohse) and in 1896 he managed to afford a visit to the Bayreuth Festival to see Wagner’s Der Ring des Nibelungen and Parsifal, both of which impressed him. In 1898, he returned to Paris to write a PhD dissertation on The Religious Philosophy of Kant at the Sorbonne, and to study in earnest with Widor. Here he often met with the elderly Aristide Cavaillé-Coll. He also studied piano at that time with Marie Jaëll. In 1899, Schweitzer spent the summer semester at the University of Berlin and eventually obtained his theology degree at the University of Strasbourg. He published his PhD thesis at the University of Tübingen in 1899.

Schweitzer rapidly gained prominence as a musical scholar and organist, dedicated also to the rescue, restoration and study of historic pipe organs. With theological insight, he interpreted the use of pictorial and symbolical representation in J. S. Bach’s religious music. In 1899, he astonished Widor by explaining figures and motifs in Bach’s Chorale Preludes as painter-like tonal and rhythmic imagery illustrating themes from the words of the hymns on which they were based. They were works of devotional contemplation in which the musical design corresponded to literary ideas, conceived visually. Widor had not grown up with knowledge of the old Lutheran hymns.

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 1905, Schweitzer began his study of medicine at the University of Strasbourg, culminating in the degree of M.D. in 1913.

The exposition of these ideas, encouraged by Widor and Munch, became Schweitzer’s last task, and appeared in the masterly study J. S. Bach: Le Musicien-Poète, written in French and published in 1905. There was great demand for a German edition, but, instead of translating it, he decided to rewrite it. The result was two volumes (J. S. Bach), which were published in 1908 and translated into English by Ernest Newman in 1911. Ernst Cassirer, a contemporaneous German philosopher, called it “one of the best interpretations” of Bach. During its preparation Schweitzer became a friend of Cosima Wagner, then resident in Strasbourg, with whom he had many theological and musical conversations, exploring his view of Bach’s descriptive music, and playing the major Chorale Preludes for her at the Temple Neuf. Schweitzer’s interpretative approach greatly influenced the modern understanding of Bach’s music. He became a welcome guest at the Wagners’ home, Wahnfried. He also corresponded with composer Clara Faisst, who became a good friend.

In 1905, Widor and Schweitzer were among the six musicians who founded the Paris Bach Society, a choir dedicated to performing J.S. Bach’s music, for whose concerts Schweitzer took the organ part regularly until 1913. He was also appointed organist for the Bach Concerts of the Orféo Català at Barcelona, Spain, and often travelled there for that purpose. He and Widor collaborated on a new edition of Bach’s organ works, with detailed analysis of each work in three languages (English, French, German). Schweitzer, who insisted that the score should show Bach’s notation with no additional markings, wrote the commentaries for the Preludes and Fugues, and Widor those for the Sonatas and Concertos: six volumes were published in 1912–14. Three more, to 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.

At the age of 30, in 1905, Schweitzer answered the call of The Society of the Evangelist Missions of Paris, which was looking for a physician. The committee of this missionary society was not ready to accept his offer, considering his Lutheran theology to be “incorrect”. He could easily have obtained a place in a German evangelical mission, but wished to follow the original call despite the doctrinal difficulties. Amid a hail of protests from his friends, family and colleagues, he resigned his post and re-entered the university as a student in a three-year course towards the degree of Doctorate in Medicine, a subject in which he had little knowledge or previous aptitude. He planned to spread the Gospel by the example of his Christian labour of healing, rather than through the verbal process of preaching, and believed that this service should be acceptable within any branch of Christian teaching.

Schweitzer was one of colonialism’s harshest critics. In a sermon that he preached on 6 January 1905, before he had told anyone of his plans to dedicate the rest of his life to work as a physician in Africa, he said:

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.

His pamphlet “The Art of Organ Building and Organ Playing in Germany and France” (1906, republished with an appendix on the state of the organ-building industry in 1927) effectively launched the 20th-century Orgelbewegung, which turned away from romantic extremes and rediscovered baroque principles—although this sweeping reform movement in organ building eventually went further than Schweitzer had intended. In 1909, he addressed the Third Congress of the International Society of Music at Vienna on the subject. Having circulated a questionnaire among players and organ-builders in several European countries, he produced a very considered report. This provided the basis for the International Regulations for Organ Building. He envisaged instruments in which the French late-romantic full-organ sound should work integrally with the English and German romantic reed pipes, and with the classical Alsace Silbermann organ resources and baroque flue pipes, all in registers regulated (by stops) to access distinct voices in fugue or counterpoint capable of combination without loss of distinctness: different voices singing the same music together.

Even in his study of medicine, and through his clinical course, Schweitzer pursued the ideal of the philosopher-scientist. By extreme application and hard work, he completed his studies successfully at the end of 1911. His medical degree dissertation was another work on the historical Jesus, The Psychiatric Study of Jesus. He defended Jesus’ mental health in it. In June 1912, he married Helene Bresslau, municipal inspector for orphans and daughter of the Jewish pan-Germanist historian Harry Bresslau.

In 1912, now armed with a medical degree, Schweitzer made a definite proposal to go as a physician to work at his own expense in the Paris Missionary Society’s mission at Lambaréné on the Ogooué river, in what is now Gabon, in Africa (then a French colony). He refused to attend a committee to inquire into his doctrine, but met each committee member personally and was at last accepted. Through concerts and other fund-raising, he was ready to equip a small hospital. In early 1913, he and his wife set off to establish a hospital (Albert Schweitzer Hospital) near an existing mission post. The site was nearly 200 miles (14 days by raft) upstream from the mouth of the Ogooué at Port Gentil (Cape Lopez) (and so accessible to external communications), but downstream of most tributaries, so that internal communications within Gabon converged towards Lambaréné.

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.

Schweitzer’s wife, Helene Schweitzer, was an anaesthetist for surgical operations. After briefly occupying a shed formerly used as a chicken hut, in late 1913 they built their first hospital of corrugated iron, with two 13-foot rooms (consulting room and operating theatre) and with a dispensary and sterilising room in spaces below the broad eaves. The waiting room and dormitory (42 by 20 feet) were built, like native huts, of unhewn logs along a 30-yard path leading from the hospital to the landing-place. The Schweitzers had their own bungalow and employed as their assistant Joseph, a French-speaking Galoa (Mpongwe) who first came as a patient.

After World War I broke out in July 1914, Schweitzer and his wife, German citizens in a French colony when the countries were at war, were put under supervision by the French military at Lambaréné, where Schweitzer continued his work. In 1917, exhausted by over four years’ work and by tropical anaemia, they were taken to Bordeaux and interned first in Garaison and then from March 1918 in Saint-Rémy-de-Provence. In July 1918, after being transferred to his home in Alsace, he was a free man again. At this time Schweitzer, born a German citizen, had his parents’ former (pre-1871) French citizenship reinstated and became a French citizen. Then, working as medical assistant and assistant-pastor in Strasbourg, he advanced his project on the philosophy of civilization, which had occupied his mind since 1900. By 1920, his health recovering, he was giving organ recitals and doing other fund-raising work to repay borrowings and raise funds for returning to Gabon. In 1922, he delivered the Dale Memorial Lectures in the University of Oxford, and from these in the following year appeared Volumes I and II of his great work, The Decay and Restoration of Civilization and Civilization and Ethics. The two remaining volumes, on The World-View of Reverence for Life and a fourth on the Civilized State, were never completed.

After the birth of their daughter (Rhena Schweitzer Miller), Albert’s wife, Helene Schweitzer was no longer able to live in Lambaréné due to her health. In 1923, the family moved to Königsfeld im Schwarzwald, Baden-Württemberg, where he was building a house for the family. This house is now maintained as a Schweitzer museum.

In 1924, Schweitzer returned without his wife, with an Oxford undergraduate Noel Gillespie as his assistant. Everything was heavily decayed, and building and doctoring progressed together for months. He now had salvarsan for treating syphilitic ulcers and framboesia. Additional medical staff, nurse (Miss) Kottmann and Dr. Victor Nessmann, joined him in 1924, and Dr. Mark Lauterberg in 1925; the growing hospital was manned by native orderlies. Later Dr. Trensz replaced Nessmann, and Martha Lauterberg and Hans Muggenstorm joined them. Joseph also returned. In 1925–6, new hospital buildings were constructed, and also a ward for white patients, so that the site became like a village. The onset of famine and a dysentery epidemic created fresh problems. Much of the building work was carried out with the help of local people and patients. Drug advances for sleeping sickness included Germanin and tryparsamide. Trensz conducted experiments showing that the non-amoebic strain of dysentery was caused by a paracholera vibrion (facultative anaerobic bacteria). With the new hospital built and the medical team established, Schweitzer returned to Europe in 1927, this time leaving a functioning hospital at work.

Recordings of Schweitzer playing the music of Bach are available on CD. During 1934 and 1935 he resided in Britain, delivering the Gifford Lectures at Edinburgh University, and those on Religion in Modern Civilization at Oxford and London. He had originally conducted trials for recordings for HMV on the organ of the old Queen’s Hall in London. These records did not satisfy him, the instrument being too harsh. In mid-December 1935 he began to record for Columbia Records on the organ of All Hallows, Barking-by-the-Tower, London. Then at his suggestion the sessions were transferred to the church of Ste Aurélie in Strasbourg, on a mid-18th-century organ by Johann Andreas Silbermann (brother of Gottfried), an organ-builder greatly revered by Bach, which had been restored by the Lorraine organ-builder Frédéric Härpfer shortly before the First World War. These recordings were made in the course of a fortnight in October 1936.

He was there again from 1929 to 1932. Gradually his opinions and concepts became acknowledged, not only in Europe, but worldwide. There was a further period of work in 1935. In January 1937, he returned again to Lambaréné and continued working there throughout World War II.

The Albert Schweitzer Fellowship was founded in 1940 by Schweitzer to unite US supporters in filling the gap in support for his Hospital when his European supply lines were cut off by war, and continues to support the Lambaréné Hospital today. Schweitzer considered his ethic of Reverence for Life, not his hospital, his most important legacy, saying that his Lambaréné Hospital was just “my own improvisation on the theme of Reverence for Life. Everyone can have their own Lambaréné.” Today ASF helps large numbers of young Americans in health-related professional fields find or create “their own Lambaréné” in the US or internationally. ASF selects and supports nearly 250 new US and Africa Schweitzer Fellows each year from over 100 of the leading US schools of medicine, nursing, public health, and every other field with some relation to health (including music, law, and divinity). The peer-supporting lifelong network of “Schweitzer Fellows for Life” numbered over 2,000 members in 2008, and is growing by nearly 1,000 every four years. Nearly 150 of these Schweitzer Fellows have served at the Hospital in Lambaréné, for three-month periods during their last year of medical school.

From 1939–1948, he stayed in Lambaréné, unable to go back to Europe because of the war. Three years after the end of World War II, in 1948, he returned for the first time to Europe and kept travelling back and forth (and once to the US) as long as he was able. During his return visits to his home village of Gunsbach, Schweitzer continued to make use of the family house, which after his death became an archive and museum to his life and work. His life was portrayed in the 1952 movie Il est minuit, Docteur Schweitzer, starring Pierre Fresnay as Albert Schweitzer and Jeanne Moreau as his nurse Marie. Schweitzer inspired actor Hugh O’Brian when O’Brian visited in Africa. O’Brian returned to the United States and founded the Hugh O’Brian Youth Leadership Foundation (HOBY).

The journalist James Cameron visited Lambaréné in 1953 (when Schweitzer was 78) and found significant flaws in the practices and attitudes of Schweitzer and his staff. The hospital suffered from squalor and was without modern amenities, and Schweitzer had little contact with the local people. Cameron did not make public what he had seen at the time: according to a BBC dramatisation, he made the unusual journalistic decision to withhold the story, and resisted the expressed wish of his employers to publish an exposé.

In 1955, he was made an honorary member of the Order of Merit (OM) by Queen Elizabeth II. He was also a chevalier of the Military and Hospitaller Order of Saint Lazarus of Jerusalem.

Schweitzer was awarded the Nobel Peace Prize of 1952, accepting the prize with the speech, “The Problem of Peace”. From 1952 until his death he worked against nuclear tests and nuclear weapons with Albert Einstein, Otto Hahn and Bertrand Russell. In 1957 and 1958, he broadcast four speeches over Radio Oslo which were published in Peace or Atomic War. In 1957, Schweitzer was one of the founders of The Committee for a Sane Nuclear Policy. On 23 April 1957, Schweitzer made his “Declaration of Conscience” speech; it was broadcast to the world over Radio Oslo, pleading for the abolition of nuclear weapons. His speech ended, “The end of further experiments with atom bombs would be like the early sunrays of hope which suffering humanity is longing for.”

Schweitzer was nonetheless still sometimes accused of being paternalistic, colonialist, and racist in his attitude towards Africans, and in some ways his views did not differ from those of many liberals and other critics of colonialism. For instance, he thought that Gabonese independence came too early, without adequate education or accommodation to local circumstances. Edgar Berman quotes Schweitzer as having said in 1960, “No society can go from the primeval directly to an industrial state without losing the leavening that time and an agricultural period allow.” Schweitzer believed dignity and respect must be extended to blacks, while also sometimes characterizing them as children. He summarized his views on European-African relations by saying “With regard to the negroes, then, I have coined the formula: ‘I am your brother, it is true, but your elder brother.'” Chinua Achebe has criticized him for this characterization, though Achebe acknowledges that Schweitzer’s use of the word “brother” at all was, for a European of the early 20th century, an unusual expression of human solidarity between Europeans and Africans. Schweitzer eventually emended and complicated this notion with his later statement that “The time for speaking of older and younger brothers has passed”.

Schweitzer died on 4 September 1965 at his beloved hospital in Lambaréné, now in independent Gabon. His grave, on the banks of the Ogooué River, is marked by a cross he made himself.

The prize was first awarded on 29 May 2011 to Eugen Drewermann and the physician couple Rolf and Raphaela Maibach in Königsfeld im Schwarzwald, where Schweitzer’s former residence now houses the Albert Schweitzer Museum.
