The People of the Abyss by Jack London - The People of the Abyss (1903) is a book by Jack London about life in the East End of London in 1902. He wrote this first-hand account by living in the East End (including the Whitechapel District) for several months, sometimes staying in workhouses or sleeping on the streets. The conditions he experienced and wrote about were the same as those endured by an estimated 500,000 of the contemporary London poor. There had been several previous accounts of slum conditions in England, most notably The Condition of the Working Class in England in 1844 by Friedrich Engels. However, most of these were based on secondhand sources. Jack London's account, however, was based on the firsthand experience of a very successful writer, and his account proved to be more popular. Jacob Riis's sensational How the Other Half Lives (1890) has been suggested as a source of inspiration for The People of the Abyss. A contemporary advertisement for Jack London's book said that it "tingles" with the "directness only possible from a man who knows London as Jacob Riis knows New York," suggesting that his publisher, at least, perceived a resemblance.
