albino

Albino comes directly from Portuguese albino (a person with congenital absence of pigmentation), from albo (white), from Latin albus (white, pale, bright). The Latin albus is one of the Indo-European words for white — distinct from candidus (gleaming white, brilliant white) and from the silver-white of argentum — and it names the dull, matte, chalky white rather than the bright or shining white. Albus gives English album (originally a white tablet for writing), alb (the white liturgical garment), albumen (the white of an egg), albedo (the measure of reflectivity in astronomy), and the name Alba (Latin name for Scotland, from its white chalk cliffs). Portuguese traders and sailors along the West African coast in the late fifteenth and early sixteenth centuries encountered Africans with albinism — the congenital absence of melanin pigment from skin, hair, and eyes caused by genetic mutations in the melanin-production pathway — and applied the term albino to them. The word is first attested in English in 1660 in Samuel Purchas's collection of travel accounts, describing people encountered by Portuguese explorers in Africa.

Albinism is a relatively rare genetic condition caused by mutations in one of several genes involved in the biosynthesis of melanin, the pigment responsible for the color of skin, hair, and eyes in humans (and in the plumage, fur, and scales of animals). In humans, the most common form is oculocutaneous albinism (OCA), which affects the pigmentation of the skin, hair, and eyes simultaneously, resulting in very pale skin, white or light yellow hair, and eyes that appear pink or blue because without melanin the retina is translucent and the blood vessels show through. The visual system is directly affected by the absence of melanin in the eye: because melanin plays a role in the development of the optic nerve pathways, albinism is typically accompanied by reduced visual acuity, sensitivity to light (photophobia), and rapid involuntary eye movements (nystagmus). In sub-Saharan Africa, where intense ultraviolet radiation is the norm, the absence of protective melanin also creates severe risks of sunburn and skin cancer.

When Portuguese sailors and traders encountered albinism in West Africa, they saw it as a remarkable anomaly — people with African features but pale, sometimes white skin — and they wrote about it with a mixture of curiosity, medical speculation, and the casual contempt of colonial observation. The African people with albinism whom the Portuguese encountered were members of communities that varied widely in their treatment of albinism: some African cultures treated albinos as sacred or spiritually powerful, others subjected them to severe discrimination or violence. Portuguese records tended to describe them as curiosities and anomalies without engaging with their social position. The term albino — the Portuguese word for 'white one' — entered European natural history and travel literature as the standard description of this condition, and it was subsequently applied by European naturalists to white animals as well: white tigers, white peacocks, white deer.

In the eighteenth and nineteenth centuries, albinism attracted intense scientific and pseudoscientific attention in the context of European theories of race. Some theorists attempted to use the existence of albinism in African populations as evidence for theories of racial hierarchy — arguing, absurdly, that albinism represented an atavistic reversion toward whiteness that supposedly demonstrated a connection between white and black populations. These theories were scientifically worthless but historically revealing: they show how the neutral Portuguese word for a pigmentation condition became entangled in the racial ideology of the period that adopted it. In the twentieth century, albinism was characterized genetically and medically, the racial theorizing was discredited, and albino was re-established as a value-neutral medical and zoological term. In human contexts, many people with albinism prefer 'person with albinism' to 'albino,' following the general preference for person-first language in disability discourse.
