Who first reported the use of magnetic fingerprint powder?

The use of magnetic fingerprint powder revolutionized the process of obtaining and processing latent prints. H. MacDonald is credited with first reporting the use of this technique. This method offered significant advantages over traditional fingerprint powders because it allowed for non-destructive application and easy removal from surfaces, making it particularly useful in preserving the integrity of potential evidence.

By utilizing magnetic properties, this technique enables investigators to apply the powder with greater precision, reducing the risk of smudging or damaging the fingerprints. This innovation marked a significant advancement in forensic science and the collection of latent prints, illustrating MacDonald’s impact on fingerprint analysis and evidence collection methods. Understanding the developments in fingerprinting techniques, such as those attributed to H. MacDonald, is essential for professionals in the field as they continue to employ and innovate forensic science methods.
