When 27-year-old José Gregorio Hernández Cisneros returned to his native Venezuela from Europe, he founded three university chairs in medicine. Despite his social prominence, he prioritized the poor: “I am not going to deny them consultations, and I am not going to make them go through the pain of telling me that they have no money,” he said. “God will help.”
Born in the Andean village of Isnotú, Hernández wanted to become a priest but pursued medicine at his family’s urging. After earning his medical degree, he continued his studies in Paris and Berlin, where he was known for his intelligence and virtue.
On returning to Caracas, he taught and practiced medicine, beginning each day with Mass and each lecture with the sign of the cross. A third-order Franciscan, he provided free consultations for impoverished patients and paid for their prescriptions out of his own pocket, earning the nickname “doctor of the poor.”
In 1908, Hernández entered a Carthusian charterhouse near Lucca, Italy, but returned to Venezuela after nine months due to ill health. He twice pursued seminary studies, first in Caracas and later in Rome, but his lifelong desire to become a priest remained unfulfilled. He ultimately devoted himself to medicine, making important contributions to immunology and bacteriology, pioneering laboratory diagnosis and treating influenza patients during the 1918 pandemic.
On June 29, 1919, Hernández was struck by a car outside a pharmacy while delivering medicine to a sick person. After receiving last rites, he called out, “Oh, Blessed Virgin,” and died at age 54.
He was canonized by Pope Leo XIV in 2025. His memorial is celebrated Oct. 26.
