Jacob Riis used the new technology of flash photography to bring the harsh realities of poverty and the squalid conditions of Manhattan tenements to light during the Gilded Age. His groundbreaking book, “How the Other Half Lives,” published in 1890, combined vivid photographs with powerful narratives that sparked a movement for social reform and better living conditions for the urban poor.
