He also studied under the Tyrolian pianist Ignaz Ladurner, who introduced him to the work of Bach and Haydn, which Boëly would champion in his adult career.
Entrenching his reactionary reputation, he used his appointment as organist at Saint Germain l'Auxerrois in 1840 to promote the works of deceased composers who were then only scantily appreciated by the public.
He died a simple piano teacher, but not without enjoying the respect and confidence of a close circle of friends which included Marie Bigot, Pierre Baillot, Friedrich Kalkbrenner, and Johann Baptist Cramer.
Although Boëly was and remains largely unknown to the public, this does not diminish the part he played in the flourishing development of French music during the 19th century.
In old age, he was sought out by two rising young artists, César Franck and Camille Saint-Saëns, who revered him as a guardian of a noble and pure classical organ tradition.
