Fingerprint classification systems included the Roscher System, the Juan Vucetich System and the Henry Classification System. The Roscher System was developed in Germany and implemented in both Germany and Japan. The Vucetich System was developed in Argentina and implemented throughout South America. The Henry Classification System was developed in India and implemented in most English-speaking countries. In the Henry Classification System there are three basic fingerprint patterns: loop, whorl, and arch, which constitute 60–65 percent, 30–35 percent, and 5 percent of all fingerprints respectively. There are also more

The Henry Classification System, co-devised by Haque and Bose, was accepted in England and Wales when the first United Kingdom Fingerprint Bureau was founded in Scotland Yard, the Metropolitan Police headquarters, London, in 1901. Sir Edward Richard Henry subsequently achieved improvements in dactyloscopy. In the United States, Dr. Henry P. DeForrest used fingerprinting in the New York Civil Service in 1902, and by December 1905, New York City Police Department Deputy Commissioner Joseph A. Faurot, an expert in the Bertillon system and a fingerprint advocate at Police Headquarters, introduced the fingerprinting of criminals to the United States.
Title: Hem Chandra Bose
Content:  On 12 June 1897, the Council of the Governor General of India approved a committee report that fingerprints should be used for classification of criminal records. After that year, the Kolkata Anthropometric Bureau became the world's first Fingerprint Bureau. He was working in the Calcutta Anthropometric Bureau (before it became the Fingerprint Bureau) with Azizul Haque. He and Haque were the two Indian fingerprint experts credited with primary development of the Henry Classification System (named for their supervisor, Edward Richard Henry). The Henry Classification System is still used in all English-speaking countries (primarily as the manual filing system for accessing paper archive files that have not been scanned and computerized).

Content:  Hemchandra Bose, Henry developed a system of fingerprint classification enabling fingerprint records to be organised and searched with relative ease. It was Haque who was primarily responsible for developing a mathematical formula to supplement Henry's idea of sorting in 1,024 pigeon holes based on fingerprint patterns. Years later, both Haque and Bose, on Henry's recommendation, received recognition by the British Government for their contribution to the development of fingerprint classification. In 1897, the Government of India published Henry's monograph, Classification and Uses of Fingerprints. The Henry Classification System quickly caught on with other police forces, and in July 1897 Victor Bruce, 9th Earl of Elgin, the Governor-General of India, decreed that fingerprinting should be made an official policy of the British Raj. This 
Title: Henry Classification System
Content:   Although fingerprint characteristics were studied as far back as the mid-1600s, the use of fingerprints as a means of identification did not occur until the mid-19th century. In roughly 1859, Sir William James Herschel discovered that fingerprints remain stable over time and are unique across individuals; as Chief Magistrate of the Hooghly district in Jungipoor, India, in 1877 he was the first to institute the use of fingerprints and handprints as a means of identification, signing legal documents, and authenticating transactions. The fingerprint records collected at this time were used for one-to-one verification only; as a means in which records would be logically filed and searched

This was the first known murder case to be solved using fingerprint analysis. In Kolkata a fingerprint Bureau was established in 1897, after the Council of the Governor General approved a committee report that fingerprints should be used for the classification of criminal records. The bureau employees Azizul Haque and Hem Chandra Bose have been credited with the primary development of a fingerprint classification system eventually named after their supervisor, Sir Edward Richard Henry.
Title: Fingerprint
Content:  Before computerization, manual filing systems were used in large fingerprint repositories. A fingerprint classification system groups fingerprints according to their characteristics and therefore helps in the matching of a fingerprint against a large database of fingerprints. A query fingerprint that needs to be matched can therefore be compared with a subset of fingerprints in an existing database. Early classification systems were based on the general ridge patterns, including the presence or absence of circular patterns, of several or all fingers. This allowed the filing and retrieval of paper records in large collections based on friction ridge patterns alone. The most popular systems used the 
Title: Dermatoglyphics
Content:  1823 marks the beginning of the scientific study of papillary ridges of the hands and feet, with the work of Jan Evangelista Purkyně. By 1858, Sir William Herschel, 2nd Baronet, while in India, became the first European to realize the value of fingerprints for identification. Sir Francis Galton conducted extensive research on the importance of skin-ridge patterns, demonstrating their permanence and advancing the science of fingerprint identification with his 1892 book Fingerprints. In 1893, Sir Edward Henry published the book The classification and uses of fingerprints, which marked the beginning of the modern era of fingerprint identification and is the basis for other classification systems. In 1929, Harold Cummins and Charles Midlo M.D., together with others, published the influential book Fingerprints, Palms and Soles, a bible in the field of dermatoglyphics. In 1945, 
Title: Fingerprint
Content:  From the late 16th century onwards, European academics attempted to include fingerprints in scientific studies. But plausible conclusions could be established only from the mid-17th century onwards. In 1686 the professor of anatomy at the University of Bologna Marcello Malpighi identified ridges, spirals and loops in fingerprints left on surfaces. In 1788 a German anatomist Johann Christoph Andreas Mayer was the first European to recognize that fingerprints were unique to each individual. In 1880 Henry Faulds suggested, based on his studies, that fingerprints are unique to a human.

Darwin was unable to assist Dr. Faulds, but agreed to forward the letter to his cousin, Sir Francis Galton. Dr. Henry Faulds and Sir Francis Galton did not engage in much correspondence, but in the following decade, they devised very similar fingerprint classification systems. It is unclear whom to credit for the classification system. However, we do know that Dr. Henry Faulds was the first European to publish the notion of scientific use of fingerprints in the identification of criminals. 

Question: who devised the fingerprint classification still used today in europe and the us?
Answer: Hem Chandra Bose.
Azizul Haque.
Sir Edward Henry.
