In 1977, the Esperanza Base was elected as the place of filing of Argentine families that traveled at the end of that year to overwinter at the base. The first director of the Argentine Antarctic Institute, general Hernán Pujato, was the forerunner of the installation of the Fortín Sargento Cabral when on 13 August 1954 he proposed the Argentine Government create a farmhouse out cape Spring to populate it with family groups. The idea had aimed to strengthen Argentine rights in that part of Antarctica.
