“ During the last 50 years he has published in Gilbert's, Poggendorff's, and Liebig's Annalen more than 250 papers on chemical subjects. Among his principal discoveries are the isolation of aluminum in 1827, of glucinum and yttrium in 1828, the artificial production of formic acid in 1829, and his investigations on nickel in 1832. ”

“ 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. ”
