Editing Castle Bank & Trust (section)

==Establishment and Operations==
Castle Bank & Trust was a Bahamian bank founded in the early 1960s by [[Paul Helliwell]], a former Office of Strategic Services (OSS) officer and later CIA operative, and Burton Kanter, a Chicago-based tax lawyer. Headquartered in Nassau, Bahamas, with operations later extending to the Cayman Islands, the bank was established as a financial institution catering to wealthy clients seeking offshore accounts for tax advantages. Its client base included celebrities like John Fogerty of Creedence Clearwater Revival, Tony Curtis, Hugh Hefner, and Penthouse magazine, as well as prominent business families like the Pritzkers (Hyatt hotel chain) and reputed organized crime figures such as Moe Dalitz, Morris Kleinman, and Samuel A. Tucker.

The bank facilitated tax evasion by providing anonymous numbered accounts, allowing clients to shield income from U.S. tax authorities. Beyond its role as a tax haven, Castle Bank became a conduit for covert financial operations, particularly for the Central Intelligence Agency (CIA). It was used to funnel funds for clandestine activities, including anti-Castro operations staged from Andros Island in the Bahamas, a key hub for CIA efforts against Cuba during the 1960s.
