Simon Sechter was an Austrian music theorist, composer, conductor, and organist. He is best known as a strict music teacher, whose many students included Anton Bruckner, Sigismond Thalberg, and Henri Vieuxtemps. In 1851, he was professor of composition at the Vienna Conservatory; after Sechter's death, his student Bruckner would succeed him and continue teaching his approach to harmony and counterpoint.
