Portrait of Mrs. Decatur Howard Miller (Eliza Credilla Hare)

Alfred Jacob Miller was a 19th-century American painter and documentarian of the American West. Working primarily in watercolor and oil, he created detailed records of Native American life, frontier settlements, and landscapes during the 1830s and 1840s, often from firsthand observation during expeditions into unexplored territories. His work serves as a visual archive of pre-industrial Western culture and the material conditions of early American expansion. Miller's studies combine ethnographic precision with romantic landscape composition, balancing documentary intent with aesthetic refinement.
