Cahill Gordon & Reindel LLP (founded 1919) is a prominent New York-based international law firm with offices in New York, Washington, D.C. and London. According to The American Lawyer, Cahill is consistently among the most profitable law firms in the world. Cahill opened its doors at 120 Broadway in 1919 as a small firm that quickly built a national reputation in the financial and corporate areas. By the end of the Depression, it had expanded to handle bankruptcies, reorganizations, and regulatory matters. During and after the Second World War, under the leadership of John T. Cahill, former United States Attorney for the Southern District of New York, the firm grew dramatically. As Cahill Gordon Reindel & Ohl, it moved to 80 Pine Street, where it remains. Partner John Ohl, a tax specialist, retired in 1976. The firm established its Paris office in 1928, though it closed in 2000 when the firm opened its London office. Today, Cahill maintains offices in London and Washington D.C., though by far its largest office is in New York City. Renowned for its corporate finance practice and work in high-stakes lawsuits, Cahill remains a successful law firm with approximately 350 attorneys. Cahills litigation practice is one of the more prominent in the United States, handling high-profile securities, antitrust and first amendment litigation. The firms partners have made frequent appearances before the United States Supreme Court. For instance, National Broadcasting Co. v. United States helped establish the power and authority of the Federal Communications Commission. Another case, Times-Picayune v. United States, is among the Courts most important antitrust rulings.
