Waldo H. Dubberstein

Waldo Herman "Doobie" Dubberstein (October 21, 1907 - April 29, 1983) was a lifelong American intelligence officer, and a scholar and professor of middle eastern studies, political science, history, and archaeology. He worked for decades at both the Defense Intelligence Agency (DIA) and Central Intelligence Agency (CIA). Dubberstein was involved with the American intelligence effort surrounding Anwar Sadat's trip to Jerusalem, border hostilities between Egypt and Libya, and the Camp David accords.

In 1983, the day after he was indicted by a grand jury on selling classified information in connection with Edwin P. Wilson and Frank Terpil, he was found dead of a shotgun blast to the head in an apparent suicide. While his death was ruled a suicide, Dubberstein's family, former colleagues, and some federal investigators suspect that he was murdered. One of four notes left to his lawyers read "I am not guilty." The contents of the other three notes are not known.
