Who was the first composer to notate a trombone smear?

Question

I've been listening to Henry Fillmore's "Trombone Family". It brought me to thinking, how long have trombone smears been around in written sheet music? Was Fillmore, a.k.a. "Father of the Trombone Smear", the first to use trombone smears or the first to popularize them? Who was the first to put them into written sheet music if he wasn't?

Answer 1

Henry Fillmore popularized the use of trombone smears (aka “glissando”) which seems to have originated in Europe and America in the 19th century. In classical orchestral music it is already found in Aleksandr Glazunov’s “The Sea” (1889), as well as in Edward Elgar’s “The Dream of Gerontius” (1899) and Arnold Schoenberg’s “Pelleas und Melisande” (1902/03). A famous trombone’s glissando passage is also in Stravinskij’s “Pulcinella” (1919/20).
