j: Conversation with "The Ghost Map" Author


Steven Johnson and Ralph Frerichs on London Cholera in 1854






In 2006, Steven Johnson, author of the recently published and soon to become a best-seller book featuring John Snow, The Ghost Map: The Story of London's Most Terrifying Epidemic - and How It Changed Science, Cities, and the Modern World and Ralph R. Frerichs, past Chair of the UCLA Department of Epidemiology, conducted a conversation at the Hammer Museum in West Los Angeles. The subject was both Johnson's book and Frerichs' extensive website on John Snow, the "father of modern epidemiology." The two had never met but were very familiar with each other's work, which became the topic of a lively conversation. The attending public audience engaged in a question and answer session towards the end of the one hour and 20 minute program.
