The article deals with the traditional bond of the Jews with medical science, especially in the Iberian Peninsula during the Middle Ages, where recognized figures of Hebrew origin practiced medicine with remarkable success in the world known at that time. What made it possible for the Jews will develop medical science in times of darkness? In addition, the validity of the profession in modern times is analyzed, particularly in the Cuban Hebrew community of the first half of the 20th century, according to the information published in the bibliographic collection Abraham Marcus Matterin, preserved by the Historical Archive of the Office of the Historian of the City of Havana.
