Harry T. Mahoney. Matthew S. Dingley and Mahoney both put their names on a memorandum on July 8, 1966, that were virtually identical to one another. The memo was on Manuel Ray Rivero (AMBANG-1) and AMBADGER-1 (Dr. Julian Gallo).

The Originating Officer for a dispatch on July 14, 1966, was Harry Mahoney. Matthew S. Dingley signed on behalf of the Chief, Western Hemisphere Division. This dispatch contained the memo from Dingley mentioned above. Alongside Earl Williamson, Mahoney worked with AMBANG-1 and AMBADGER-1. Furthermore, a dispatch in October of 1958 stated that "in the past, both Gerende (Ramon Joseph Alvarez Durant) and Scantling have evidenced a high degree of loyalty to Matthew S. Dingley, their former Station Case Officer." Anne Goodpasture's Mexico City Station History mentioned that Harry Mahoney requested an operational clearance for Raymond H. Gerende, and the latter became involved in the LIFEAT Project. Mahoney met Gerende in 1954.

Control - All LIEMPTY agents are local nationals. Gerende and Scantling, both of whom spent a great deal of their childhood years in PBPRIME (U.S.) and still have relatives living in PBPRIME, are in many respects more pro-PBPRIME than many PBPRIME citizens. In the past, both Gerende and Scantling have evidenced a high degree of loyalty to Matthew S. Dingley, their former Station Case Officer, and appear to be devoting that same loyalty to the present Case Officer. The control over Gerende and Scantling stems directly from their pro-PBPRIME beliefs and their personal loyalty to their past and present Case Officers..."

07/13/66: Memorandum for the record from Matthew S. Dingley: Subject: AMBADGER-1: "1. On this date, Subject called me from San Juan, Puerto Rico to report on his meeting with AMBANG-1 on 12 July. AMBANG-1 remained adamant concerning his refusal to reveal the names of his sources inside Cuba. However, AMBADGER-1 believes that AMBANG-1 is in a better frame of mind than previously and he needs some added push to reveal the names. 2. AMBADGER suggested that Growery come to Puerto Rico to give AMBANG-1 that added push. AMBADGER-1 said that AMBANG-1 speaks fondly of Growery and he believes that Growery might convince AMBANG-1 to reveal the names. Alternatively, AMBANG-1 and AMBADGER-1 could come to Washington, D.C. for discussions with Growery. 3. I agreed to write AMBADGER-1 the details of processing his wife's citizenship. AMBADGER-1 wants to process his wife's citizenship in Montreal. I also agreed to look into the matter of transmitting money to his mother in Cuba at a rate of exchange more favorable than one to one."

11/16/78: Mexico City Station History by Anne Goodpasture: Pages 20-21: ..."In early 1954, while Harry T. Mahoney and his wife were occupying temporary quarters after their arrival in Mexico City, a young Mexican-American student tapped on the door one day. He introduced himself to Mahoney's wife as a student at Mexico City College. He explained that his mother was an American schoolteacher, and that he was working his way through college by selling eggs, chickens, and cheese to people in the apartment building where the Mahoneys lived. That evening Mahoney learned about the egg salesman and stayed home the next day to meet him. After that meeting, Mahoney checked citizenship files in the Embassy and gathered enough background information for a request for an operational clearance. The salesman was Raymond H. Gerende (201-119523) who became the principal agent for the photographic bases, acted as a transcriber for LIFEAT, alternated as a handler for the unilateral surveillance teams, and performed various other operational tasks from 1955 until 1970..."
