Thomas Say

Thomas SAY (27a de Junio, 1787 – 10a de Oktobro, 1834) estis usona entomologo, konkologo, kaj herpetologo. Liaj studoj pri insektoj kaj konkoj, nombraj kontribuoj al sciencaj gazetoj, kaj sciencaj ekspedicioj al Florido, Georgio, la Roka Montaro, Meksiko, kaj aliloken faris lin internacie konata natursciencisto. Say estis nomita la patro de usonaj priskribaj entomologio kaj konkologio. Li servis kiel bibliotekisto de la Akademio de Naturaj Sciencoj de Filadelfio, zorganto de la Usona Filozofia Societo (elektita en 1817), kaj profesoro de natura historio en la Universitato de Pensilvanio. and professor of natural history at the University of Pennsylvania.Mallis, 1971Pitzer, 1989

Kariero
Say helpis en la fondo de la Akademio de Naturaj Sciencoj de Filadelfio (ANSP) en 1812. In 1816, li renkontiĝis kun Charles Alexandre Lesueur, franca natursciencisto, malakologo, kaj iĥtiologo kiu tuj iĝis membro de la Akademio kaj servis kiel ĝia zorganto ĝis 1824.

En la Akademio, Say eklaboris por la American Entomology. Por kolekti insektojn, li faris nombrajn ekspediciojn al landlimaj areoj, riskante atakojn de indiĝenoj kaj akcidentojn pro veturado en sovaĝa kamparo. En 1818, Say akompanis sian amikon William Maclure, tiam prezidanto de la ANSP kaj patro de la usona geologio; Gerhard Troost, ankaŭ geologo; kaj aliajn membrojn de la Akademio al geologia ekspedicio ĉe insuloj de Georgio kaj Florido, tiam hispana teritorio.

En 1819–20, Stephen Harriman Long estris esploradon al la Roka Montaro kaj al alfluantoj de la rivero Misuro, kun Say kiel zoologo. Ilia oficiala rakonto de tiu ekspedicio inkludis la unuajn priskribojn de kojoto, de la vulpo Vulpes velox, la tiranedo Tyrannus verticalis, la Strivosta kolombo, la Salpinkto, la tiranedo Sayornis saya (kiu portas la nomon de Say kaj en la genronomo kaj en la specia nomo), la Malgranda kardelo, la Alaŭdopasero, la lazurulo Passerina amoena, la Oranĝkrona vermivoro, la lacertoj Aspidoscelis tesselata kaj Crotaphytus collaris, la skinko Scincella lateralis, kaj la serpentoj Pantherophis obsoletus kaj Thamnophis proximus.

Lea. 503 pp. 

En 1823, Say estis ĉefa zoologo en la ekspedicio de Long al la ekfluo de la rivero Misisipo. Li veturis en la "Boatload of Knowledge" al la kolektiveco New Harmony en Indianao (1826–34), eksperimento de utopia societo fondita de Robert Owen. Say estis akompanita de Maclure, Lesueur, Troost, kaj Francis Neef, plinoviga pedagogo. Tie li poste renkontiĝis kun Constantine Samuel Rafinesque-Schmaltz, alia natursciencisto.
