Although the metal was not isolated until the 19th cent., use of aluminum compounds originated in antiquity. The Romans used various aluminum compounds as astringents; they called these alum. Sir Humphry Davy and other chemists in the early 19th cent. recognized aluminum as the metal and alumina as its oxide. H. C. Oersted succeeded in obtaining impure aluminum in 1825, but Friedrich Wöhler had greater success and is usually credited with its first isolation, in 1827. H. E. Sainte-Claire Deville first prepared inexpensive pure metal in 1854 and set about perfecting a process for its commercial production. However, it was not until 1886 that the process by which aluminum is produced today was discovered independently by C. M. Hall, a student at Oberlin College, and Paul Héroult, a French metallurgist.
