West Germany In 1979, Eli Rosenbaum of the Office of Special Investigations (OSI) by chance read about Rudolph in a book about moving rocket parts using forced labor. Rosenbaum had conducted research at the National Archives, about the Dora war crimes trial, appearing to connect Rudolph with the use of forced labor at Mittelwerk. In September 1982, Rudolph received a letter requesting an interview by the OSI. Rudolph believed this was one of the series of interrogations he had gone through since his arrival in the U.S. The first of three interviews, it centered on his attitudes on racial superiority, his early participation in the Nazi Party and a possible role in the treatment of prisoners at Mittelwerk. On November 28, 1983, Rudolph, purportedly, according to his attorneys, under duress and fearful for the welfare of his wife and daughter, signed an agreement with the OSI stating that he would leave the United States and renounce his United States citizenship. Under the agreement, Rudolph would not be prosecuted, the citizenship of his wife and daughter was not in danger of revocation and Rudolph's retirement and Social Security benefits were left intact. In March 1984 Arthur and Martha Rudolph departed for West Germany where Rudolph renounced his citizenship as agreed. West Germany protested to the United States Department of State, as Rudolph now had no citizenship in any country. In July, West Germany requested documentation from the OSI to determine if Rudolph should be prosecuted or granted citizenship. The World Jewish Congress placed articles in newspapers in January 1985 on behalf of the Department of Justice, searching for survivors of the Mittelwerk. After receiving documentation in April 1985, the case was investigated by Harald Duhn, the Attorney General of Hamburg. In March 1987, the investigation concluded after questioning a number of witnesses and determining no basis for prosecution, since the only crime which had not passed the statute of limitations was murder. Rudolph was granted West German citizenship. Meanwhile, a great deal of controversy occurred back in the U.S. Rudolph had not told his friends of the investigation, but the OSI issued a press release after his departure. Several groups and individuals were calling for an investigation into the OSI's activities regarding Rudolph. These included retired Major General John Medaris (former commander of ABMA), officials of the city of Huntsville, the American Legion and former associates at NASA. Thomas Franklin interviewed
