Victorian London's slums—Whitechapel, St. Giles, Jacob's Island—were human catastrophes.
Families packed into single rooms without water, ventilation, or sewage. Cholera, typhus, and tuberculosis ran rampant.
Gangs ruled alleys; women and children faced constant assault. The 1888 Jack the Ripper murders epitomized the terror.
Casual dock work, matchstick-making, and prostitution were often the only income. Children labored instead of attending school.
Investigative journalism (Mayhew, Booth), the Public Health Acts, and philanthropic housing (Peabody Trust) began slow improvement—yet shadows lingered into the 20th century.
