Edward Henry was the Inspector-General of Police in Bengal in the 1890s and the Commissioner of Scotland Yard after 1903. This paper is a study of Edward Henry's work as the acting Commissioner of Police on the Witwatersrand between August 1900 and April 1901. The paper argues that Henry's role was extra-ordinary in the Reconstruction Era, and that the South African obsession with fingerprinting as the basis of administrative identification dates from this time.
