Gustavo Gutierrez became the president of the Comite Cubano Pro-Palestina (Hebreo), established in early 1944. It was located on Teniente Rey No. 405, Havana. The vice-presidents were Carlos Prio Socarras, Rafael Guas Inclan and Juan L. Martin. Its secretary was Ofelia Dominguez. The vice-secretary was Felix Pita Rodriguez; treasurer was Miguel Angel Cespedes and vice-treasurer; Antonio Martinez Bello. Exact dates of its inception are not available yet some experts (Ignacio Klich) speculate as early as January or February or April. Upon viewing the photograph it is obvious that the "Comité" was in full swing by the summer since many of the man are wearing Cuba's traditional summer attire (white "Dril Cien" Irish linen suits) at this committee luncheon. Gustavo is seated seventh from the right facing the camera. His wife, Maria Vianello is seated to his left. No other individual is identifiable.
Some documentation obtained from the Georgetown University follows. The letters below add some information regarding this committee. The American Palestine Committee located in Washington, DC was headed by Senator Robert Wagner and Charles McNary. Gustavo Gutierrez wrote the Americans thanking them for their congratulatory letter regarding Cuba's creation of a pro Jewish Palestine committee, adding that, "The distinguished group of political and intellectual leaders that constitute this committee, is a good proof of the sentiment of the Cuban people towards the recognition of the Jews to enjoy the equality of rights everywhere and to the reconstitution of Palestine as their national home."
