Albert Demangeon was born on 13 June 1872 in Cormeilles, Eure, France.^[1] His parents were not well off but Albert was an outstanding student and won admission to the École Normale Supérieure in 1892. There he became interested in geography and in the teachings of Paul Vidal de La Blache. He graduated in geography in 1895 and became a teacher in a secondary school. He later was employed in the École Normale Supérieure preparing students for the Agrégation.^[2]

Demangeon presented his thesis on Picardy in 1905, considered a model of a regional monograph. He obtained a teaching post at the University of Lille.^[2] He collaborated with Antoine Vacher, Joseph Blayac and others on their Dictionnaire-manuel illustré de géographie (1907). The book received hostile reviews, and Demangeon seems to have accused Vacher of sabotaging the project.^[3] From 1911 he taught in Paris at the Sorbonne. During World War I (1914–18) Demangeon served in the geographical corps of the army and drafted memos for the army staff. Towards the end of the war he was a member of the committee studying preparation for peace.^[2] The "section géographique française" helped define the policies that France would follow after the war on territorial arrangements.^[4]

Demangeon returned to the Sorbonne after the war.^[2] He was Professor of economic geography at the Faculty of Letters from 1925 to 1940.^[1] He served on the editorial board of the Revue d'Histoire Moderne, which was relaunched in 1926.^[5] By 1927 he was one of the directors of Armand Colin's Annales de Géographie.^[6] Demangeon was noted as a university teacher, and also contributed to primary education.^[2] He was responsible for a well known collection of secondary school textbooks.^[7] In the mid-1930 he taught at the École des hautes études commerciales de Paris (HEC). One of his students was the future economist Albert O. Hirschman, who recorded that he gave "brilliant lectures", and used large and colorful maps to illustrate his themes of commerce and trade between geographical regions, and the resulting economic rivalries.^[8] Demangeon acted as an arbitrator in social conflicts at the time of the Popular Front (1936–38).^[2]

Demangeon's daughter Suzanne married the geographer Aimé Vincent Perpillou (1902–76), who also became a distinguished economic geographer.^[9] Albert Demangeon died on 25 July 1940 in Paris, France.^[1]

Demangeon was a prolific author. His pre-war work focused on physical regional geography, but later he also wrote on larger topics including several volumes of the Géographie Universelle published under the direction of Paul Vidal de La Blache and Lucien Gallois. At the Sorbonne he turned from physical to human geography.^[2] He avoided theoretical work, and did not write a book about the general subject of human geography, although his writings on the subject were published after his death in Problems of Human Geography (1942).^[2] This collection of his main articles covered a broad spectrum of human geography topics.^[7]

Demangeon was interested in the interactions of man and nature, and also in history, although he felt that geography must remain a distinct subject.^[2] He wrote in 1906, "To explain the geographical phenomena of which man has been the witness or contriver, it is necessary to study their evolution in the past with the aid of documents." Later he defined three principles for the study of human geography:^[10]

1. It should avoid determinism. Causes are always complex and involve human initiative and choice.
2. It should be based upon a territorial unit. To understand and describe regional units is one of the main objectives of geographical study.
3. It must consider not only the present day. The idea of age and of evolution is indispensable. Without it, the reason for what exists often escapes us.

Demangeon's 1905 study of Picardy had a strong historical element, reflecting Vidal de la Blache's emphasis on the role of man in changing the face of the earth. Also in 1905 he produced a valuable guide to the National Archives for the use of geographers.^[11] He cooperated with historians, and coauthored The Rhine, Problems of History and Economy (1935) with Lucien Febvre.^[7] He studied current issues such as colonialism, globalization, the Great Depression and German ambitions.^[2] His Le déclin de l'Europe (1920) was published in the US in 1921 under the title America and the Race for World Domination. It argued that Europe was deeply in debt and exhausted by the war, with reduced agricultural and industrial output, and low birth rates. The US and Japan had expanded their industries, replaced Europe's exports with their own, and were owed huge sums in exchange for the supplies they had shipped to Europe during the war.^[4]

Demangeon wrote several studies of cities, but was more interested in the country, and also in economics.^[2] Throughout his career Demangeon was interested in spatial variations of farmsteads.^[12] He presented a famous study of rural houses to the 1st International Congress of Folklore in 1937.^[7] His two-volume work France Économique et Humaine, published posthumously in 1944 and 1948, surveyed the rural life and economy, road, railway and canal routes and their traffic, coastal and inland towns, industry and Paris.^[13] There are in-depth surveys of agriculture, towns and industry for each region. Throughout the work there is a historical flavour with references to evolution of land use, development of routes, evolution of industry, changes to urban area.^[14]

Demangeon used a precise vocabulary and linked observed facts in order to formulate new questions. He made use of questionnaires to investigate patterns as early as 1909. In the 1930s he used questionnaires in large surveys for a 1939 study of foreigners in French agriculture.^[7] The surveys, sponsored by the Rockefeller Institute, gathered information on rural habitat, the organization of farms and the use of foreign farm labour.^[2]
