He did some performing in Germany and Belgium, then became a piano teacher at the Cologne Conservatory in 1871, where he had a long career. He conducted the Cologne Musical Society.

Dedications to Isidor Seiss included:

Edvard Grieg: Book III of the Lyric Pieces

He wrote some educational pieces for piano and other minor works. He also arranged some of Beethoven's Contredanses and German Dances for piano. He also revised Weber's Piano Concerto No. 2 in E-flat, and published editions of Mendelssohn's Capriccio brillante in B minor, and other works.
Isidor Seiss died by his own hand in Cologne in 1905, having suffered increasing blindness that had forced him to retire from his teaching position. Although aged only 64, he had outlived his entire family, and in his will he endowed the Conservatory with a pension and cash grants for the four oldest teachers. He also bequeathed over half a million marks to the city of Cologne.
