Little is known of Horace Warner and nothing is known of his relationship to the nippers. Only 30 of these pictures survive, out of 240 he took in 1912 of the Spitalfields Nippers, East End London. They originally accompanied the annual reports of the charitable Bedford Institute, Quaker St, Spitalfields as illustrations of poverty, "but that is not the sum total of these beguiling photographs...spirited images of something more subtle and compelling, the elusive drama of childhood itself."
Portraits of new arrivals were used as a marker of a child's progress in the Society. Case studies of some children appeared in the newsletter 'Our Waifs and Strays' describing how they had been transformed from a 'potential street loafer' into a productive member of society. These studies were often illustrated with 'before and after' photographs, contrasting their ragged past with their new-found respectability.
