José Gregorio Hernández Cisneros OFS (Spanish: [xoˈse ɣɾeˈɣoɾjo eɾˈnandes]; 26 October 1864 – 29 June 1919) was a Venezuelan physician.

[2] José Gregorio Hernández Cisneros was born on 26 October 1864 in Isnotú, a small village in the state of Trujillo in Venezuela.

He spent the entirety of his childhood in his hometown, where his mother worked as a housekeeper and his father sold pharmaceuticals and livestock.

[6] After completing his high school education, Hernández enrolled in the Central University of Venezuela in Caracas to begin his medical studies.

Hernández traveled to Paris, where he studied other fields of medicine such as: bacteriology, pathology, microbiology, histology, and physiology.

[citation needed] With the arrival in 1918 of the highly contagious Spanish flu in Venezuela, Hernández treated patients in Caracas who had caught it.

[2] Blessed José Gregorio Hernández is also revered by Venezuela's alternative and syncretic religion, the cult of Maria Lionza.

[10][14] Historian Steven Palmer also has drawn parallels between the Hernández cult and that of the assassinated Costa Rican physician and politician Ricardo Moreno Cañas.
