Judge Benjamin Barr Lindsey's exposé of big business's influence on Colorado and Denver politics caused a sensation when serialized in Everybody's Magazine 1909-1910. When published as a book later in 1910, The Beast was considered every bit the equal of Upton Sinclair's The Jungle. Now back in print, the book reveals the plight of working-class Denver citizens - in particular, those Denver youths who ended up in Lindsey's court day after day. These encounters led him to create Denver's Juvenile Court, one of the first courts in the country set up to deal specifically with young delinquents. In addition, Lindsey exposes the darker sides of many well-known figures in Colorado history, including Mayor Robert W. Speer, industrialist and Senator Simon Guggenheim, and Denver tramway czar William Gray Evans. More than just a fascinating slice of Denver history, this book - and Lindsey's court - inspired widespread social change in the United States.
