Gustav Bock popularized the cigar band in the early 19th century due to the emergence of a trade in counterfeit Havana cigars, where cheaper German-made cigars were being passed off as Cuban cigars. Uniquely made cigar bands, each style registered with the Cuban government, assured the authenticity of Cuban cigars to buyers. When legendary psychoanalyst Sigmund Freud was challenged on the phallic shape of the more than 20 Cuban cigars that he smoked daily, he replied, "Sometimes a cigar is just a cigar." His cigar habit was the primary cause of Freud's cancer that required the partial removal of his jaw. Even after this operation, he continued to smoke his beloved Cuban cigars. In 1960, the CIA's Office of Medical Services was told to treat a box of Fidel Castro's favorite cigars with botulinus toxin, a lethal poison. In early 1961, the CIA decided against the poisoned cigars. Instead, they gave American organized crime figure, John Rosselli, botulinus toxin pills to pass on to a Cuban confederate who was closely tied to Castro. He is, however, still alive and in 1963, the Cohiba cigar brand was launched in tribute to revolutionary leader Fidel Castro. When it was first introduced, the brand was reserved only for friends of the Revolution. It was released for commercial sale to the public in 1982. The Cohiba factory is the first cigar factory staffed exclusively with women cigar rollers.
