| OtherInfo | Agassiz came under the tutelage of Alexander von Humboldt (FRS 1815), who later became his benefactor. Agassiz had a profound influence on his areas of scientific research, namely natural sciences especially geology, glaciology and ichthyology. Numerous geological areas and locations are named after him, for example the Agassizhorn in Bernese Alps, Switzerland. Several animal species are also named after him, mainly fish. His much improved classification system of fish, which divided them into four categories, has since been superseded. He was a frequent correspondent and collaborator with a variety of contemporary scientists, e.g. the botanist Asa Gray (FRS 1873), who, unlike Agassiz, was a firm supporter of Darwin's theories on humans' common evolutionary ancestry.
After his move to the United States, Agassiz became a strong proponent of polygenism, believing that all races were created separately and that there existed a set hierarchy of races, with white people, in particular of Germanic or Anglo-Saxon origin at the top and Black people at the bottom. He advocated for racial segregation and called for legislation to prevent mixed race procreation, something he considered sinful. His ideas of scientific racism were frequently used by defenders of slavery. In 1850, he commissioned what are considered the first known photographs of enslaved persons, daguerrotypes depicting Renty Taylor and his daughter Delia. The photographs were then given to Harvard University, who licensed the photos for use in the late 20th century. The University was sued by Tamara Lanier, a descendant of Renty Taylor's, and her lawsuit was supported by 43 living descendants of Agassiz. |
