[3] He served as a special agent for the Federal Bureau of Investigation in 1933 and 1934, the highlight of his career there being his participation in an unsuccessful attempt to capture John Dillinger at Little Bohemia Lodge.

He was assistant to five successive United States Attorneys General (Homer Cummings, Frank Murphy, Robert Jackson, Francis Biddle and Tom Clark) from 1938 to 1945.

[5] In 1942, he was sent to Hartford to prosecute a major spy ring case in which five men (Anastasy Vonsiatsky, Wilhelm Kunze, and others) were accused of violating the Espionage Act of 1917 by conspiring to gather and deliver US Army, Navy, and defense information to Germany or Japan.

Both Supreme Court Justice Robert H. Jackson, chief prosecutor for the U.S., and Dodd insisted upon a fair and legal trial to prosecute the Nazi war criminals.

Dodd suggested Heidelberg as the location for the International Military Tribunal, since it had survived the war almost completely unscathed, but Nuremberg was eventually chosen.

"[8] Dodd cross-examined defendants Wilhelm Keitel, Alfred Rosenberg, Hans Frank, Walther Funk, Baldur von Schirach, Fritz Sauckel and Arthur Seyss-Inquart.

[5] Through his evidence, Dodd showed that Erich Koch, the Reichskommissar for Ukraine, and defendant Hans Frank, the Governor-General of Poland, were responsible for the plan to deport one million Poles for slave labor.

[9] He also showed evidence that defendant Walther Funk turned the Reichsbank into a depository for gold teeth and other valuables seized from the concentration camp victims.

Dodd showed a motion picture of the vaults in Frankfurt where Allied troops found cases of these valuables, containing dentures, earrings, silverware and candelabra.

These six organizations were the Leadership Corps of the Nazi Party, the Reich Cabinet, the Gestapo, the Storm Troopers (SA), the Armed Forces, and the Elite Guard (SS).

[3] In 1949, the Polish government had intended to award Dodd with a badge of honor called the Officer's Cross of the Order of Polonia Restituta, but Dodd rejected the medal due to his commitment to human rights and views that the Polish government was imposing a tyranny similar to that imposed by the Nazis, and accepting an honor from the President of Poland would be like accepting one from the Nazis.

[20] In 1964, Dodd was locked in a somewhat bitter and tough re-election bid against popular former Governor John Davis Lodge, the younger brother of the Ambassador to South Vietnam and former U.S.

It also allowed Johnson that much more excitement in naming a running mate, a choice that had come down in the press and public opinion between Humphrey and Minnesota's other senator, the urbane Eugene McCarthy.

[24] As chairman of the Senate Subcommittee on Juvenile Delinquency, Dodd worked to restrict the purchase of mail order handguns and later shotguns and rifles.

[25] Dodd played an instrumental role in the prohibition of LSD in the United States by presiding over subcommittee hearings purportedly investigating the drug's effects on youth.

Although Leary urged lawmakers to enact a strictly regulated framework in which LSD would remain legal, Dodd and his colleagues drafted a ban which was later adopted.

[28][29] Beyond the Senate Ethics Committee's formal disciplinary action, other sources (such as investigative journalist Drew Pearson and Jack Anderson's Congress in Crisis) suggest[30] Dodd's corruption was far broader in scope, and there were accusations of alcoholism.
