Arthur D. Little is an international management consulting firm originally headquartered in Boston, Massachusetts, United States, founded in 1886 and formally incorporated in 1909 by Arthur Dehon Little, an MIT chemist who had discovered acetate. Arthur D. Little pioneered the concept of contracted professional services. The company played key roles in the development of business strategy, operations research, the word processor, the first synthetic penicillin, LexisNexis, SABRE, and NASDAQ. Today the company is a multinational management consulting firm operating as a partnership. Early history The roots of the company were started in 1886 by Arthur Dehon Little, an MIT chemist, and co-worker Roger B. Griffin (Russell B. Griffin), another chemist and a graduate of the University of Vermont who had met when they both worked for Richmond Paper Company. Their new company, Little & Griffin, was located in Boston where MIT was then located. Griffin and Little prepared a manuscript for The Chemistry of Paper-making which was for many years an authoritative text in the area. The book had not been entirely finished when Griffin was killed in a laboratory accident in 1893. Little, who had studied Chemistry at MIT, collaborated with MIT and William Hultz Walker of the MIT Chemistry department, forming a partnership, Little & Walker, which lasted from 1900 to 1905, while both MIT and Little's company were still located in Boston. The partnership dissolved in 1905 when Walker dedicated all of his time to being in charge of the new Research Laboratory of Applied Chemistry at MIT. Little continued on his own and incorporated the company, Arthur D. Little (ADL), in 1909. He conducted analytical studies, the precursor of the consulting studies for which the firm would later become famous. He also taught papermaking at MIT from 1893 to 1916. In 1917, the company, originally based at 103 Milk Street in Boston, moved to its own building, the Arthur D. Little Inc., Building, at 30 Memorial Drive on the Charles River next to the new campus of MIT, which had also relocated from Boston to Cambridge. The building was added to the National Register of Historic Places in 1976. In November 1953, ADL opened a 40-acre site for its Acorn Park labs in west Cambridge, Massachusetts, about 6 miles (10 km) from MIT. The new site took its name from the company motto - "Glandes Sparge Ut Quercus Crescant," translated as "Scatter Acorns That Oaks May
