André Lafosse was a professional trombonist and professor at the Paris Conservatoire in the early 20th century. He wrote a book entitled Méthode complète pour le trombone in three volumes published in 1921 (first two volumes) and 1946 (third volume). In it he famously describes the practise of playing with vibrato as vulgar and glissandos of questionable taste.
