Which of the following scientist developed a method to transfer latent fingerprints on surfaces to paper using iodine fuming ?
Paul-Jean Coulier
Iodine fuming is one of the oldest chemical methods for developing latent fingerprints. Iodine crystals sublime on gentle warming, and the violet vapour is absorbed by the fatty and oily components of the latent print, producing yellowish-brown ridges.
In 1863, the French chemist Paul-Jean Coulier of Val-de-Grâce, Paris, published a method of developing latent prints on paper with iodine fumes and described how such prints could be preserved and transferred, and examined with a magnifying glass.
Francis Galton classified fingerprint minutiae and proved their individuality. William Herschel used handprints and fingerprints on contracts in Bengal from 1858. Behnam Bavarian worked on modern electrochemical development of prints on metal. None of them introduced iodine fuming transfer.
Hence, the answer is Paul-Jean Coulier.
