Gustave Frédéric Dollfus

Gustave Frédéric Dollfus (26 November 1850, Paris – 6 November 1931, Paris)[1] was a French geologist and malacologist. He was the father of parasitologist Robert-Philippe Dollfus (1887–1976).

In 1868–70 he studied geology under Edmond Hébert at the Sorbonne, then continued his education in Lille as a pupil of Jules Gosselet. In 1879 he began work at the Service de la carte géologique de la France (Department of French geological cartography).[2]

He was twice chosen as president of the Société de géologie de France (1896 and 1916).[3] In 1923 he was awarded the Lyell Medal by the Geological Society of London.[4]

His name is associated with several species of mollusk, an example being Chrysallida dollfusi, a sea snail described by Wilhelm Kobelt in 1903.[5] The World Register of Marine Species lists 272 marine species named by Dollfus. [6]

Research

Among his various geological studies was analysis of the Cretaceous and Tertiary in the Cotentin Peninsula (mid-1870s). From his research of the Aquitanian stage, he published an important essay titled "Essai sur l'étage Aquitanien" (1909). With Philippe Dautzenberg, he was co-author of the voluminous "Conchyliologie du Miocéne moyen du Bassin de la Loire" (Conchology in regard to the Middle Miocene of the Loire basin). Other significant works by Dollfus include:

  • Principes de géologie transformiste, application de la théorie de l'évolution à la géologie, 1874 - Principles of geological transformism, application of the theory of evolution to geology.
  • Essai sur l'extension des terrains tertiaires dans le bassin anglo-parisien, 1880 - Essay on the extension of Tertiary terrain in the Anglo-Paris basin.
  • Esquisse des terrains tertiaires de la Normandie, 1880 - Sketch involving the Tertiary terrain of Normandy.
  • Descriptions de coquilles nouvelles des faluns de la Touraine, 1888 - Descriptions of new coquilles in the faluns of Touraine.
  • Recherches géologiques sur les environs de Vichy (Allier), 1894 - Geological research on the environs of Vichy (Allier).
  • Mollusques tertiaires du Portugal, 1909 - Terrestrial mollusks of Portugal.[2][7]
