Frank J. Hogan opened his law practice in Washington, D.C. in 1904, quickly earning fame as America's leading trial lawyer as a result of a string of successes in high-profile, politically charged cases. In 1924 Hogan represented oil magnate Edward L. Doheny who had been indicted in the "Teapot Dome" scandal on charges of bribery and conspiracy to defraud the United States. Doheny was acquitted, while Secretary of the Interior Albert Fall was found guilty of accepting the bribe. Such cases earned Hogan a national reputation as the most famous trial lawyer in the country and attracted Nelson T. Hartson, former solicitor of internal revenue, to the firm in 1925 to establish a business practice to complement the firm's established trial practice. Continued growth and success led to the 1938 partnership between Hogan and Hartson.
Throughout the next half-century, the firm continued to expand and distinguish itself in numerous areas. As the activities of the federal government expanded, the number and scope of Hogan & Hartson's practice areas also grew. While litigation (both trial and appellate), taxation, health, and communications remained major focuses of the firm's practice, many other areas were also added over the years, including all significant aspects of corporate, regulatory, intellectual property, and legislative.
In the 1970s, Hogan & Hartson became the first major law firm in the United States to establish a separate practice group devoted exclusively to providing pro bono legal services.
The beginning of a major evolutionary shift for Hogan & Hartson came in 1984 with the opening of the firm's first office outside of the district. The rest, as they say, is history. By April 2010, the firm had 26 offices in 12 countries on four continents.
