Merriam Webster

Merriam-Webster is not an individual author but an American company founded in 1831 by brothers George and Charles Merriam in Springfield, Massachusetts, as G & C Merriam Co.[1] The company became renowned for dictionaries after purchasing the rights to Noah Webster's *An American Dictionary of the English Language* in 1843 following his death, establishing itself as the oldest dictionary publisher in the United States.[1]
