In his day, Johann Sebastian Bach was better known as a virtuoso organist than as a composer. His sacred music, organ and choral works, and other instrumental music had an enthusiasm and seeming freedom that concealed immense rigor. Bach's use of counterpoint was brilliant and innovative, and the immense complexities of his compositional style -- which often included religious and numerological symbols that seem to fit perfectly together in a profound puzzle of special codes -- still amaze musicians today. Many consider him the greatest composer of all time.

Bach was born in Eisenach in 1685. He was taught to play the violin and harpsichord by his father, Johann Ambrosius, a court trumpeter in the service of the Duke of Eisenach. Young Johann was not yet ten when his father died, leaving him orphaned. He was taken in by his recently married oldest brother, Johann Christoph, who lived in Ohrdruf. Because of his excellent singing voice, Bach attained a position at the Michaelis monastery at Lüneberg in 1700. His voice changed a short while later, but he stayed on as an instrumentalist. After taking a short-lived post in Weimar in 1703 as a violinist, Bach became organist at the Neue Kirche in Arnstadt (1703-1707). His relationship with the church council was tenuous as the young musician often shirked his responsibilities, preferring to practice the organ. One account describes a four-month leave granted Bach to travel to Lubeck, where he would familiarize himself with the music of Dietrich Buxtehude. He returned to Arnstadt long after he was expected and much to the dismay of the council. He then briefly served at St. Blasius in Mühlhausen as organist, beginning in June 1707, and married his cousin, Maria Barbara Bach, that fall. Bach composed his famous Toccata and Fugue in D minor (BWV 565) and his first cantatas while in Mühlhausen, but quickly outgrew the musical resources of the town. He next took a post for the Duke of Sachsen-Weimar in 1708, serving as court organist and playing in the orchestra, eventually becoming its leader in 1714. He wrote many organ compositions during this period, including his Orgel-Büchlein, and also began writing the preludes and fugues that would become Das wohltemperierte Klavier (The Well-Tempered Klavier). Owing to politics between the Duke and his officials, Bach left Weimar and secured a post in December 1717 as Kapellmeister at Köthen. In 1720, Bach's wife suddenly died, leaving him with four children (three others had died in infancy). A short while later, he met his second wife, soprano Anna Magdalena Wilcke, whom he married in December 1721. She would bear 13 children, though only five would survive childhood. The six Brandenburg Concertos (BWV 1046-51), among many other secular works, date from his Köthen years. Bach became Kantor of the Thomas School in Leipzig in May 1723 (after the post was turned down by Georg Philipp Telemann) and held the position until his death. It was in Leipzig that he composed the bulk of his religious and secular cantatas. Bach eventually became dissatisfied with this post, not only because of its meager financial rewards, but also because of onerous duties and inadequate facilities. Thus he took on other projects, chief among which was the directorship of the city's Collegium Musicum, an ensemble of professional and amateur musicians who gave weekly concerts, in 1729. He also became music director at the Dresden Court in 1736, in the service of Frederick Augustus II; though his duties were vague and apparently few, they allowed him the freedom to compose what he wanted. Bach began making trips to Berlin in the 1740s, not least because his son Carl Philipp Emanuel served as a court musician there. The Goldberg Variations, one of the few pieces by Bach to be published in his lifetime, appeared in 1741. In May 1747, the composer was warmly received by King Frederick II of Prussia, for whom he wrote the gloriously abstruse Musical Offering (BWV 1079). Among Bach's last works was his 1749 Mass in B minor. Besieged by diabetes, he died on July 28, 1750. ~ Robert Cummings

Karl Richter was regarded as one of the great Bach conductors of the twentieth century, noted for solid regularity in rhythms and a serious approach to the music, though he was not given to following the changing pronouncements of musicologists concerning historical accuracy in performance.

He was brought up in the tradition of German Protestant religious music; his father was a minister in the central German regions near where Johann Sebastian Bach had lived. Richter learned piano and organ, and as he approached his 12th birthday entered the Kreuzschule school in Dresden. After World War II, he entered the Leipzig Conservatory, where he studied with Rudolf Mauersberger, and also studied at the Leipzig Institute for Sacred Music, where he learned Bach interpretation from Karl Straube and Günther Ramin. Very soon he was appointed choirmaster of the Christuskirche in Leipzig at the age of 20, and in 1947 became the organist of the Thomanerkirche, both institutions with strong Bach traditions.

He left East Germany in 1950 to live in West Germany and settled in Munich, where he was organist of the Markuskirche and started teaching that same year at the Hochschule für Musik of Munich. He organized the Munich Bach Choir in 1951, and in 1953 added to it the Munich Bach Orchestra. His performances naturally centered on Bach and under Richter his musicians and singers became one of the most renowned organizations specializing in the music of the great German master and his era.

The formation of the Munich Bach Chorus and Orchestra reflected a growing international interest in music of the Baroque and, sparked by the advent of the LP record, the notion of integral series of composers' works. Deutsche Grammophon's Archiv label was the first of such historic specialty sub-labels. Richter and his Bach Choir and Orchestra became a major pillar of that label and recorded numerous Bach choral works, gaining international recognition.

They toured frequently, and Richter also played and recorded often as an organist and harpsichordist. In 1968, Richter made one of his most dramatic guest conducting tours when he conducted the St. John Passion and the B minor Mass in both Moscow and Leningrad at a time when religious music of any sort was rarely heard in the Soviet Union.

Although his regularity of tempo (some called it inflexibility) placed him apart from the Romantic manner of performing Bach, Richter's performances otherwise retained the Romantic era's approach, stressing the solemnity of Bach's music and including dramatic large-scale dynamic contrasts. Newer research and the growing popularity of "original" or "period" instrument performances did not affect his interpretations, which used modern instruments. In some respects, younger interpreters who emerged in the 1970s considered him the representative of an approach against which they were reacting.

Later in his career, Richter enlarged his repertory to conduct Classical, and even Romantic, era works, but tended to remain known primarily as a Baroque specialist. He is best remembered for his mastery of Baroque choral/orchestral works of the largest scale, where his architectural approach to the music is most effective. His recordings of the Bach Passions, oratorios, B minor Mass, and Magnificat, as well as Handel oratorios such as the Messiah, are considered his most important contribution to the Baroque discography.
