Samuel Kummer was born in Stuttgart in 1968. After receiving his diploma from the lycée he studied church music at the Staatliche Hochschule für Musik und Darstellende Kunst in Stuttgart. In the organ classes of Christoph Bossert, Werner Jacob and Ludger Lohmann he acquired a broad repertoire of music in many styles, which is complemented by his ability in the field of organ improvisation - he studied improvisation with Willibal Bezler, Wolfgang Seifen and Hans Martin Corrinth. During his studies he took part in many master classes. Upon his graduation in 1997 he received an award for organ improvisation.

Since 1988 Samuel Kummer has given organ recitals in Germany and elsewhere, appearing in such countries as the Netherlands, the Baltic states, Poland, Hungary, Russia, the USA and Central America. He has played in important concert series such as the European Organ Festival at Maastricht, the International Bach Festival at Warsaw, in Riga Cathedral, in the St. Petersburg Philharmonia and the Mormon Tabernacle, Salt Lake City. In 2005 he appeared again at the Cathedral in Guatemala City, where he had played in 1999 in aid of the restoration and upkeep of the historic Walcker organ of 1937.

Samuel Kummer is a prizewinner at international organ competitions. In 1996 he won the 1st prize at the "Concours L'Europe et L'Orgue" at Maastricht.

From 1998 to 2005 Kummer was District Choirmaster at the Martinskirche in Kirchheim/Teck. Numerous oratorio performances under his direction, most recently Frank Martin's "In Terra pax", and his "Organ Music at Market Time" series met with a warm response.

In 2005 Samuel Kummer was appointed organist of the Dresden Frauenkirche. He is co-initiator of the "Dresden Organ Cycle", a joint organ recital series presented at the Kreuzkirche, Hofkirche and Frauenkirche in Dresden.

As a soloist Samuel Kummer appeared with the Chemnitz Philharmonic in 2007. His CD of organ works by Bach and Duruflé, released by Carus-Verlag at the end of 2005, earned him unanimous praise from the international specialist press. Soon after its release it was already rated in the classical charts.
