Johann Pachelbel  (1653 - 1706) was a leading organist and composer, who knew the Bach family, and even taught Johann Sebastian Bach's elder brother. He wrote much organ  music, as his career was primarily as organist at various famous cathedrals in Germany. He also wrote a fair amount of notable chamber music. Since 1970, his Canon and Gigue in D has become a baroque hit, particularly because it was used in a number of TV adverts and film soundtracks at that time. It is a fine piece of music, though probably over-rated, since no-one ever hears anything else written by him these days.
