Melville Dewey: Melville Louis Kossuth Dewey was born in Adams Center, New York in the United States on December 10, 1851. Dewey invented the Dewey Decimal Classification (DDC) system for library classification when he was 21 and working as a student assistant in the library of Amherst College. This classification system is the most widely used library classification scheme in the world. In 1884, he founded the Columbia School of Library Economy, the first ever institution organized for the instruction of librarians.
He was an advocate of the metric system and English language spelling reform and is responsible for, among other things, the “American” spelling of the word Catalog (as opposed to the British Catalogue). He also considered changing his own name from Melville Louis Kossuth Dewey to simply Melvil Dui. Dewey is a member of the American Library Association’s Hall of Fame. His work created a revolution in library science and set in motion a new era of librarianship. He well deserves the title of “Father of Modern Librarianship”. He died after suffering a stroke on December 26, 1931 at an age of 80.
