“Umr bhar bojh uthaya us ‘keel’ ne;
Aur log tareef ‘tasveer’ ki karte rahe”
(It is the nail that took all the burden — yet people kept on appreciating the picture alone)
— Piyush Mishra
Writers Building in Kolkata houses the world’s oldest Fingerprinting Bureau. It was instrumental in rolling out, what came to be known as, the Henry Classification System — named after Sir Edward Henry, Inspector-General of Police of Bengal.
Today, nearly all the nations of the world follow it for maintaining criminal records. It also paved the way for the modern biometric system. However, the lesser-known fact about Henry Classification System is that two Indians, namely, Hem Chandra Bose and Qazi Azizul Haque, were majorly responsible for developing it.
