The American Cyclopædia — Wöhler…
“ In 1824 he made the tour of Sweden and Norway with Berzelius and Alexandre and Adolphe Brongniart. He returned to Frankfort in October, and undertook to continue the translation of Berzelius's Jahresbericht which Gmelin had begun. There he met Liebig, in association with whom he carried on many of his most important researches. On the foundation of the Gewerbschule in Berlin in March, 1825, Wöhler was appointed instructor in chemistry, and in 1827 he was made professor. ”
