Winthrop, Stimson, Putnam & Roberts was a prominent New York law firm that traced its origins to a law partnership formed in New York in 1868. It merged with the San Francisco based law firm Pillsbury Madison & Sutro in 2001. That firm subsequently became Pillsbury Winthrop Shaw Pittman in 2005.
The firm produced many leaders in law, jurisprudence and public service. Elihu Root, one of the firm's founders and a U .S. Secretary of State; Felix Frankfurter, legal scholar and US, Supreme Court justice; and Henry L. Stimson, cabinet member under four Presidents of the United States, are among the prominent attorneys who practiced at Winthrop Stimson.
