In the Romantic era, Leipzig became a center of trombone pedagogy. The trombone began to be taught at the Musikhochschule founded by Felix Mendelssohn Bartholdy. The Paris Conservatory and its yearly exhibition also contributed to trombone education. At the Leipzig academy, Mendelssohn's bass trombonist, Karl Traugott Queisser, was the first in a long line of distinguished professors of the trombone. Several composers wrote works for Quiesser, including Ferdinand David (Mendelssohn's concertmaster) who wrote in 1837 the "Concertino for Trombone and Orchestra", Ernst Sachse and Friedrich August Belcke, whose solo works remain popular in Germany. Queisser helped re-establish the reputation of the trombone in Germany. He championed and popularized Christian Friedrich Sattler's tenorbass trombone during the 1840s, leading to its widespread use in orchestras throughout Germany and Austria.
