August Gottfried Ritter

Co-creator, together with Felix Mendelssohn Bartholdy, of the first example of Romantic Organ Sonata (the first one was composed in 1845); he moved in 1847 from being organist in Merseburg cathedral to become organist in Magdeburg Cathedral. He also was "Royal-Prussian organ auditor". Ritter organized to build a new main organ in Magdeburg Cathedral and designed the stoplist. The organ with four manuals, mechanical key action and 81 stops was built by Adolf Reubke in 1856 to 1861.[1]

In his critical writings, Ritter condemned the Renaissance organ composers referred to as the "Colorists" for overindulging in ornamentation.
