preventing unauthorized negotiations from undermining the government's position. As chairman of the Senate Subcommittee on Juvenile Delinquency, Dodd worked to restrict the purchase of mail order handguns and later shotguns and rifles. Those efforts culminated in the Gun Control Act of 1968, which Dodd introduced, including certain registration requirements. 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. Notably, the Harvard psychologist and LSD proponent Timothy Leary was called to testify. 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. That event was one episode in the prelude towards an all-out "War on Drugs" in the 1970s. Senate censure and loss of office In 1967 Dodd became the first Senator censured by the US Senate since Joseph McCarthy in 1954, and was one of only six people censured by the Senate in the 20th century. The resulting censure was a condemnation and finding that he had converted campaign funds to his personal accounts and spent the money. 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 Dodd's corruption was far broader in scope, and there were accusations of alcoholism. In response to these accusations, Dodd filed a lawsuit against Pearson claiming that Pearson had illegally interfered with his private property. Although the district court granted a partial judgment to Dodd, the appellate court ruled in favor of Pearson on the grounds that Dodd's property had not been physically abused. In 1970, the Democrats endorsed for his seat Joseph Duffey, who won the nomination in the primary. Dodd then entered the race as an independent, taking just under a quarter of the vote, in a three-way race which he and Duffey lost to Republican Lowell Weicker. Dodd finished third, with 266,500 votes–far exceeding Weicker's 86,600-vote margin over Duffey. Death and legacy Months after his defeat, Dodd died of a heart attack at his home. His son Christopher Dodd was elected to the Senate as a Connecticut Democrat in 1980. Thomas J. Dodd Memorial Stadium in Norwich was named in his honor. In 1995, the Thomas J. Dodd Research Center was established at the University of Connecticut. The Thomas J. Dodd Research Center
