The People of the Abyss (1903) is a book by Jack London, containing his first-hand account of several weeks spent living in the Whitechapel district of the East End of London in 1902. London attempted to understand the working-class of this deprived area of the city, sleeping in workhouses or on the streets, and staying as a lodger with a poor family. The conditions he experienced and wrote about were the same as those endured by an estimated 500,000 of the contemporary London poor.
