Grant’s fel­low con­ser­va­tion­ists sup­port­ed his racist activism. Roo­sevelt wrote Grant a let­ter prais­ing “The Pass­ing of the Great Race,” which appeared as a blurb on lat­er edi­tions, call­ing it “a cap­i­tal book; in pur­pose, in vision, in grasp of the facts our peo­ple most need to real­ize.” Hen­ry Fair­field Osborn, who head­ed the New York Zoo­log­i­cal Soci­ety and the board of trustees of the Amer­i­can Muse­um of Nat­ur­al His­to­ry (and, as a mem­ber of the U.S. Geo­log­i­cal Sur­vey, named the Tyran­nosaurus rex and the Veloci­rap­tor), wrote a fore­word to the book. Osborn argued that “con­ser­va­tion of that race which has giv­en us the true spir­it of Amer­i­can­ism is not a mat­ter either of racial pride or of racial prej­u­dice; it is a mat­ter of love of coun­try.”
