Guillermo Hernández-Cartaya
Guillermo Hernández-Cartaya was a Cuban banker born sometime in 1932 (the New York Times described him in 1977 as in his "mid-fifties"); he spent 20 years as a banker in Cuba. == Bay of Pigs fiasco == He first became notable when in 1961, after having previously joined the Brigade 2506/Operation 40 organization and participating in the Bay of Pigs Invasion (possibly in revenge for Fidel Castro having destroyed his livelihood; Cartaya had been on very good terms with the former rulers of Cuba), he was sentenced to three years in jail for his part in the invasion.
