He was taught the organ from 1874 to 1877 by Josef Rheinberger and attended the choir lessons of Franz Wüllner in Munich. Immediately after that, he moved to Dresden, where he was appointed director and teacher for music theory and choral music at the Dresden School of Music.

Music
Koessler composed over 130 works, including an opera, two symphonies, symphonic variations for orchestra, a violin concerto, two string quartets, a string quintet, a string sextet, a piano quintet, a suite for piano, violin and viola, and a mass for female choir and organ. He also set psalms to music. However, as a result of his erratic way of living, a large number of his compositions were lost, or found themselves only being played in private hands.

Koessler's chamber music has been highly praised by several commentators, including the eminent chamber music scholar Wilhelm Altmann, who has singled out Koessler's Second String Quartet and his Trio Suite for Piano, Violin and Viola for especial praise.
