Humboldt also recommended Buschmann to the royal library in Berlin, where he became an assistant in 1832. After Humboldt's death in 1835, Buschmann was the sole author of the third volume, which contained a comparative grammar of the South Sea and Malay languages. The Berlin Academy put him in charge of editing the whole work (3 vols., Berlin, 1836-1840). Buschmann also published Humboldt's vocabulary of the Tahitian language in his "Aperçu de la langue des îles Marquises et la langue taïtienne" (1843).
