Hahn & Hahn's History

On September 1, 1899, Benjamin W. Hahn and his brother, Edwin F. Hahn, opened a law partnership they called Hahn & Hahn. It was the turn of the century, and in Washington D.C., William McKinley became the first U.S. President to ride in a horseless carriage. In the South Pacific, the Spanish-American War reached its conclusion with the signing of the Treaty of Paris. From Italy, Guglielmo Marconi introduced the world to the wireless telegraph and was preparing to broadcast the first Transatlantic radio signal. And in the fledgling City of Pasadena, California, itself barely ten years old, Hahn & Hahn opened a small office in the Wetherby & Kayser Building, located on a wide dirt road named Colorado Boulevard. Building on a reputation of honesty and integrity, the new partnership flourished. Benjamin and Edwin, the former now also serving as Los Angeles County's representative to the State Senate, were joined in 1917 by Benjamin's son, Herbert L. Hahn, recently graduated from Stanford Law School. Following Edwin's appointment to the Superior Court bench in 1921, the law firm moved to the newly-constructed Pacific-Southwest Building at the corner of Colorado and Marengo Boulevards, where it would remain until 1964, when the firm moved to its current location at 301 East Colorado Boulevard.
