A selective guide to botanical publications and collections with dates, commentaries and types. Supplement V: Da-Di.'' Koeltz Scientific Books, Königstein 1998, ISBN 3-87429-402-1.〕 He was the son of botanist and mycologist Pierre Augustin Dangeard and brother of geologist and oceanographer, Louis Dangeard. == Biography == Pierre Dangeard was born on 18 February 1895 in Poitiers, France. Four years earlier his father had relocated from Caen to take up a botany professorship at the ''Academie des Sciences'', the scientific faculty of the University of Poitiers, and a year after his move, had married the 20-year-old Henriette Louise Labrosse.〔(GeneaNet ): Genealogy of the Dangeard family, French, visited 15 April 2011〕 Dangeard was the second of four siblings. His elder brother Henri died in 1899 at the age of six. Pierre thus became the eldest of the children and followed in his father's footsteps to become a botanist. In 1909 the family moved to Paris after Dangeard's father was offered and accepted a position at the prestigious ''Academie des Sciences''. After receiving a baccalaureate, Dangeard began to study biology at the University of Paris. In 1914 he finished with the ''license''. From 1915 to 1918 Dangeard fought in the First World War and was wounded. In 1922 he was appointed a member of the Legion of Honor. After his military service and his recovery Dangeard continued his nature studies. In 1923 he received a doctorate and published his doctoral thesis〔Pierre Dangeard: ''Recherches de biologie cellulaire. Évolution due système vacuolaire chez les végétaux.'' In: ''Le Botaniste'', vol.15, issue 1, 1923.〕 in his father's magazine ''Le Botaniste''.〔(Biodiversity Heritage Library: P.-A. Dangeard (Editor): ''Le Botaniste.'' Facsimile of the volumes 1(1889) – 15(1923), French, visited 19 April 2011 )〕 In October 1924 Dangeard was married to Madeleine Colin (1899 - 1944). They had one daughter, Geneviéve. However, Colin wife died in 1944. Three years later, in March 1947, Dangeard married again, this time to Anne Marie Coville (1908 - 1998) with whom he had a son, Bernard. After earning his PhD, Dangeard remained in Paris and in 1928 received an appointment as an assistant at the Faculty of Science, later graduating to a professorship chair of botany in 1932 at the ''Faculte des Sciences'' of the University of Bordeaux.〔Vitus Grummann (Hrsg.): ''Biographisch-Bibliographisches Handbuch.'' Cramer, Lehre 1974, ISBN 3-7682-0907-5.〕 Dangeard specialized in marine algae. He took part in various marine expeditions conducted by Jean Charcot and his research vessel Pourquoi pas?. He is thought to have worked closely with his brother, geologist and oceanographer Louis Dangeard, who also took part in marine expeditions. After his retirement from the chair of the Department of Botany at Bordeaux University, Dangeard lived in Pléneuf-Val-André, Brittany. He died on 23 August 1970 at the age of 75. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pierre Dangeard」の詳細全文を読む スポンサード リンク
