Sometimes spelled Segert. Bohemian organist, who was born at Repin, i Bohemia, and was taught music by Czernohorsky and Felix Benda at Prague, where he attended the University. Seger became organist of St. Martin's Church; afterward of the Teinerkirche at Prague, and died shortly before the news of his appointment by Joseph II. as organist of the Court Chapel at Vienna reached him. He numbered among his pupils many who afterward became famous, and was considered an excellent organist and teacher. He wrote eight toccatas and a fugue for the organ, which were published. His other music, including many masses, litanies, psalms, and motets, still remains in manuscript.
