"London Labour and the London Poor, Vol. 1" by Henry Mayhew is a work of Victorian journalism published in 1851. Through detailed interviews and forensic observation, Mayhew documents the lives of London's working poor—from rat catchers and street sellers to mudlarks scouring the Thames and pure-finders collecting dog dung. His vivid descriptions capture the chaos of street markets and the desperate ingenuity of thousands surviving in the world's richest city, combining personal testimonies with statistical analysis to reveal a forgotten underworld of poverty and resilience.
