Max Leopold Wagner (17 September 1880 – 9 July 1962) was a German philologist and ethnologist, particularly known for his studies on the Sardinian language. He also carried out pioneering research on the Spanish language in Hispanic America. In a posthumous review of his three-volume Dizionario etimologico sardo, Ernst Pulgram wrote: It can only be hoped that ... there will arise ... men like Wagner: original thinkers, deep specialists, and great synthesizers of knowledge all at the same time.[1]
