Emory Roy Buckner (August 7, 1877 -- March 11, 1941) was a prominent U.S. lawyer who served as the United States Attorney for the Southern District of New York, where he gained a reputation as one of the greatest prosecutors in American history. During his time at Root, Clark & Bird (which subsequently became Dewey Ballantine), he was also one of the architects of modern Wall Street's legal culture.
Buckner was born in Pottawattamie County, Iowa, on August 7, 1877, the son of the Reverend James Dysart Monroe Buckner (1855–1934) and Sarah Adeline Ellis (1859–1941). He was raised in Nebraska, and at age 15 completed a shorthand course, after which he spent three years in Oklahoma as a traveling court reporter. He graduated from the University of Nebraska–Lincoln in 1904. When he contacted the dean of the University of Nebraska–Lincoln College of Law, Roscoe Pound, about attending law school, Pound encouraged Buckner to attend Harvard Law School and raised money to help pay Buckner's way. Buckner graduated near the top of his class in 1907, and established a close friendship with Felix Frankfurter which would prove to be lifelong.
A Republican, he worked for Henry L. Stimson, who was then the United States Attorney for the Southern District of New York. Afterwards, he was an assistant to Charles S. Whitman, who was then the New York County District Attorney. He first gained prominence in the district attorney's office when he was chosen to conduct a highly publicized investigation into corruption allegations at the New York Police Department.
