Arthur Hays Sulzberger was the publisher of xxThe New York Timesxx from 1935 until 1961 and chairman of the board of The New York Times Company from 1961 until 1968. While he was publisher, circulation of The Times almost doubled; the editorial page developed a reputation for strong opinions; news events were subjected to more analysis and coverage of specialized topics was strengthened; new sections and departments were created for food, fashion, and women; and the overall style of the paper became less rigid and more aesthetically pleasing. The papers document Sulzberger's life and career at xxThe New York Timesxx, with the majority of the collection relating to Sulzberger's 26 years as president and publisher of the paper. Included in the collection are correspondence with family members, friends, colleagues, world leaders, and other dignitaries; memoranda regarding the business of the newspaper, including Sulzberger's notes of praise and criticism to his editors, managers, and writers; reports on his meetings with world leaders, including Winston Churchill, Dwight D. Eisenhower, Franklin D. Roosevelt, and Harry S. Truman; and photographs of Sulzberger, his family, business trips, vacations, and The Times' buildings.
