London experienced great change during the life of John Snow. The city grew dramatically between 1813 and 1858, and was at the center of a financial and social empire which reached around the world. Yet during these same years, residents of London suffered greatly from death and disease, including epidemic cholera. In addition they faced extensive environmental pollution, most notably of the majestic River Thames.
