Pseudonym: Nebecker, Joel
A memo in February of 1954 stated that "Nebecker will travel to LINCOLN (CIA's Guatemalan covert operations headquarters, a forward base in Florida) the week of 22 February to work with members of the LINCOLN staff on implementation of the PBSUCCESS labor program."
A telegram on Operation PBSUCESS in Guatemala in March of 1954 stated that Nebecker was developing plans for a proposed hemisphere wide anti-communist conference scheduled for April 15, and a exile labor meeting scheduled for May 1, 1954. This was mentioned in the KUGOWN (Psychological and Paramilitary Staff) section of the telegram.
Joel N. Nebecker was possibly Chief of Station, Rio de Janeiro in March of 1961. Moreover, Larry Staunton was an alias used by Joel N. Nebecker when meeting John Thomas Duncan in August of 1968: https://www.maryferrell.org/showDoc.html?docId=151040&relPageId=45
A cable on November 6, 1969, mentioned that Nebecker was Deputy Chief of Station (DCOS), WH/Miami. In addition, a document in January, 1970, stated that AMCHALK-5 (Miguel Angel Diaz Isalgue) knew Joel N. Nebecker's true first name. A-5 also knew Frederick C. Bradspies's true first name.
