Cleary Gottlieb Steen & Hamilton LLP (known as Cleary Gottlieb) is an American multinational law firm headquartered at One Liberty Plaza in New York City. Known as a white shoe law firm, Cleary employs over 1,200 lawyers worldwide. History The firm was founded in 1946 when six partners from the firm of Root, Clark, Buckner & Howland left to found a firm which they initially called "Cleary, Gottlieb, Friendly, & Cox." One of those partners was Henry Friendly, whose name was removed from the firm's name after he was appointed as a judge on the United States Court of Appeals for the Second Circuit in 1959. Melvin Steen was among the founding partners. The firm has been more active on large merger and acquisitions deals involving Russian companies under sanctions or restrictions than any other law firm since 2010. The firm advised Russian state-owned energy groups Rosneft and Gazprom. Offices The New York office is situated in One Liberty Plaza, across the street from the World Trade Center site.
