Robert Morris Morgenthau was an American lawyer. From 1975 until his retirement in 2009, he was the District Attorney for New York County, having previously served as United States Attorney for the Southern District of New York throughout much of the 1960s on the appointment of John F. Kennedy. At retirement, Morgenthau was the longest-serving district attorney in the history of the State of New York.

Henry Morgenthau Jr. was the United States Secretary of the Treasury during most of the administration of Franklin D. Roosevelt. He played a major role in designing and financing the New Deal. After 1937, while still in charge of the Treasury, he played the central role in financing United States participation in World War II. He also played an increasingly major role in shaping foreign policy, especially with respect to Lend-Lease, support for China, helping Jewish refugees, and proposing measures to deindustrialize and ethnically cleanse a massive portion of the German population.
