Stefan Kopeć (Jan 22,1888 – † March 11, 1941〔M. Manowski, (Bartoszewski (1970 ) ''et al'') 〕) was a Polish biologist and pioneer of insect endocrinology, who studied at the Jagiellonian University in Kraków. He received his PhD. there in 1912, and worked at Puławy Agricultural Research Station in Poland between 1915 and 1920. In 1929 he was made Director of the Institute.〔(Sláma, Karel, ''Insect Endocrinology: A Tribute to Stefan Kopeć'' ), from ''Historical figures in Insect Physiology'', University of California, Riverside, retrieved 2011-10-07. This article originally appeared on pages 11-15 of ''Insects, Chemical, physiological and evironmental aspects, Wydawnictwo Univwersytetu Wrocławskiego'', ed. By Danuta Konopińska, University of Wrocław, 1995.〕 Between 1908 and 1927, Kopec published at least 17 papers, in Polish, English and German, on insect endocrinology in various professional journals.〔 ==Biography== Kopeć began his studies of the moulting of insects with ''Lymantria Dispar'' 〔Albert Rosenfeld (books.google.co.uk ) LIFE 6 Oct 1958 (magazine) (2011-12-18 )〕 from specimens caught in the wild.〔Susan E Fahrbach, Karen A Mesce ( mendeley.com website ) ''"Neuroethoendocrinology": integration of field and laboratory studies in insect neuroendocrinology.'' Hormones and Behavior (2005) Volume: 48, Issue: 4, Pages: 352-359 (2011-12-19 )〕 His subsequent scientific activities helped determine the role of the insect brain in hormone production. He was the earliest researcher to understand the importance of the insect brain, as is demonstrated by his statement in a 1917 paper: Kopec's most significant contribution was his study of neurosecretory cells in the brains of insects which secrete a crucial growth hormone, prothoracicotropic hormone (PTTH), which regulates the process of metamorphosis (''ecdysteroidogenesis'').〔Kopeć, S. 1922.

This discovery stimulated further scientific research leading to the establishment of the field of science known as neuroendocrinology.〔Gerald Litwack (books.google.co.uk ) ''Insect Hormones'' Volume 73 of Vitamins and hormones ''Gulf Professional Publishing'', 5 Dec 2005 ISBN 0127098739, 304 pages〕〔John L.

He was imprisoned at the Pawiak Prison in Warsaw and executed by the Germans in 1941 at Palmiry,〔 near Warsaw, together with his son as a reprisal against an action of the Polish underground army, as a part of the German AB-Aktion in Poland. The University of Wrocław named its annual International Conference on Arthropods the ''Stefan Kopeć Memorial Conference'' in Kopec's honor.〔(Welcome to VII-th International Conference )〕 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「Stefan Kopec」の詳細全文を読む スポンサード リンク
