Nathaniel Southgate Shaler (1841-1906) studied at Harvard College and then went on to become a professor in paleontology there. Although he was from Kentucky, he served in the Union Army as an officer during the Civil war. However, he was an apologist for slavery, and in an 1884 Atlantic Monthly article stated that slavery in the US had been “infinitely the mildest and most decent system of slavery that ever existed.” This racism influenced his own teachings. Initially a creationist, he later became a proponent of Lamarckian theories, and an espouser of Aryan supremacy.
