Johann Anton Kobrich (1714-1791) was the priest and organist of the parish church of Landsberg am Lech in upper Bavaria from 1730 until his death. A prolific composer, Kobrich wrote several works for organ, including the Wohlgeubter Organist (1762), a three-part collection of preludes, fugues, and toccatas. The major portion of this thesis consists of an edition of twenty-six selected pieces from the original fifty-eight in this collection. Also included are a bibliography of Kobrich, a discussion of his significance among other contemporary composers, and a survey of the organs and organ music of eighteenth-century southern Germany. In addition, there is an analysis of the Wohlgeubter Organist and a commentary on its significance.
