photography and fingerprints
Photography

The invention of photography gave the new forces a way of keeping picture records of criminals. In the 1850s the first "mug-shots" were taken by professional photographers, but the police soon acquired their own cameras and extensive picture records began to be kept. Offender photographs and descriptions (including scars and other distinguishing marks) were published in the "Police Gazette" and circulated between forces

Fingerprints

Fingerprinting was introduced at Scotland Yard in 1901. Originally fingerprints were used as a way of making the criminal record of an offender available. However, as no two people have the same prints copies were soon taken from known criminals and used to identify them at the scene of later crimes.
