Ramón Emeterio Betances, Puerto Rican ophthalmologist, journalist, and politician (d. 1898)
Ramón Emeterio Betances y Alacán (April 8, 1827 – September 16, 1898) was a Puerto Rican independence advocate and medical doctor. He was the primary instigator of the Grito de Lares revolution and is considered to be the father of the Puerto Rican independence movement. Since the Grito galvanized a burgeoning nationalist movement among Puerto Ricans, Betances is also considered "El Padre de la Patria" (Father of the [Puerto Rican] Nation). Because of his charitable deeds for people in need, he also became known as "El Padre de los Pobres" ("The Father of the Poor").

Betances was also a medical doctor and surgeon in Puerto Rico, and one of its first social hygienists. He had established a successful surgery and ophthalmology practice. Betances was also an abolitionist, diplomat, public health administrator, poet, and novelist. He served as representative and contact for Cuba and the Dominican Republic in Paris, France.

An adherent of Freemasonry, his political and social activism was deeply influenced by the group's philosophical beliefs.
