George Ord

George Ord, Jr. (March 4, 1781 – January 24, 1866) was an American zoologist who specialized in North American ornithology and mammalogy. Based in part on specimens collected by Lewis and Clark in the North American interior, Ord's article "Zoology of North America''"'' (1815), which was published in the second American edition of William Guthrie's ''Geographical, Historical, and Commercial Grammar'' (Johnson and Warner), has been recognized as the "first systematic zoology of America by an American".

Ord (1815) published the first scientific descriptions of Pronghorn antelope (''Antilocapra americana''), Grizzly bear (''Ursus arctos horribilis'')'','' Meadow vole (''Microtus pennsylvanicus''), Bushy-tailed woodrat (''Neotoma cinerea''), Eastern gray squirrel (''Sciurus carolinensis pennsylvanicus''), Columbian ground squirrel (''Urocitellus columbianus''), Black-tailed prairie-dog (''Cynomys ludovicianus''), Bonaparte's gull (''Chroicocephalus philadelphia''), Ring-billed Gull (''Larus delawarensis''), Tundra swan (''Cygnus columbianus''), and Columbian sharp-tailed grouse (''Tympanuchus phasianellus columbianus'').

Ord is widely known for challenging the works of John James Audubon. Provided by Wikipedia
