Naturalist. McCrady was born in Charleston on October 15, 1831, the third of fourteen children of the attorney Edward McCrady and Louisa Rebecca Lane. After receiving his basic education in Charleston, McCrady attended the College of Charleston from 1846 to 1850. A superior student, he was strongly influenced by the Charleston lectures of Louis Agassiz and, at various times between 1852 and 1855, attended the Lawrence Scientific School of Harvard College to study with that renowned naturalist. On September 1, 1859, he married Sarah Dismukes. The couple had six children.<\/p>\n
Although he published some descriptions of fossil echinoderms and presented papers on other topics, McCrady was mainly interested in hydrozoans and jellyfish. In fact, his lengthy monograph \u201cGymnopthalmata of Charleston Harbor,\u201d which was presented before Charleston\u2019s Elliott Society of Natural History in 1857 and later published in the first volume of the proceedings of that society, earned him an enduring place as a pioneer in hydrozoan zoology. Of McCrady\u2019s taxa (scientific descriptions), two families, five genera, and thirteen species are valid today. McCrady\u2019s detailed and clear descriptions and his excellent illustrations are especially notable. Widely recognized in his field, McCrady\u2019s name is affixed to several species described by later zoologists.<\/p>\n
While his scientific studies, most of which he presented before the Elliott Society, were acknowledged by his Charleston peers, McCrady gained wider recognition during the late 1850s as a proponent of a science of racial differences. Though later refuted as unscientific, his publications won acclaim among defenders of slavery. Rejecting the sound scientific arguments of his fellow Charlestonian and noted mammalogist John Bachman that all humans constitute a single species, McCrady followed his teacher Agassiz in maintaining that the nonwhite races were separate and inferior creations. McCrady\u2019s essays, published in Charleston\u2019s Russell\u2019s Magazine <\/em>and elsewhere, represented the efforts of an able naturalist to articulate a cultural position in scientific terms.<\/p>\n A passionate champion of secession, McCrady served as an officer in the army of the Confederacy. Devastated by the failure of the movement, he suffered severe depression and eventually resigned the faculty post he had held at the College of Charleston since 1855. Recognizing him as a brilliant student of science, however, Agassiz persuaded McCrady in 1873 to accept a position at Harvard\u2019s prestigious Museum of Comparative Zoology. Agassiz died a few months later, and McCrady became professor of zoology at Harvard. Frequently ill and troubled by his perception that Yankee supporters and liberal religious views prevailed at Harvard, McCrady resigned in 1877 and joined the faculty of the University of the South in Sewanee, Tennessee. He devoted much of his time to formulating what he called a law of development and to criticizing Charles Darwin\u2019s theory of evolution.<\/p>\n After another illness, McCrady died in Nashville, Tennessee, on October 16, 1881. His body was returned to Sewanee for burial. Although he believed that he had been largely forgotten, McCrady left a lasting legacy through his contributions to science.<\/p>\n Stephens, Lester D.
