Seitz studied violin first under Karl Wilhelm Uhlrich in Sondershausen, Germany; he later married Uhlrich's daughter. He became a student of Johann Christoph Lauterbach in 1874. He became music director at Sondershausen, and thereafter became concertmaster at Magdeburg. In 1884 he was the "Hofkonzertmeister" (conductor of the court orchestra) at Dessau.
Movements from Seitz' student concerti (No. 2 and No. 5) have become more widely known by virtue of their inclusion in the Suzuki violin method instructional material.
