Pedro Evangelista Llamas, born in the town of Pagsanjan, Laguna on August 1, 1884, is the son of Gabriel Llamas and Eleutera Evangelista, both natives of Pagsanjan.
He studied at St. Joseph Catholic School in Hong Kong for two years and then went to the United States where he obtained the degree of Bachelor of Science in Pharmaceutical Chemistry from the University of Michigan.
On August 26, 1912, he married Josefa Gomez Francia, a member of a prominent Pagsanjan family, the daughter of Don Prudencio Francia and Doña Andrea Gomez. They were blessed with nine children: Herminio, Guadalupe, Fidel, Amor, Luis, Jose, Mario, Carlos, and Eva.
He was elected Municipal President of Pagsanjan in 1916-1920. After his term, though the people wanted to re-elect him for the second term but he refused because of his failing health.
He founded the Pagsanjan Academy in 1923 to serve his own people. Later, he thought of putting up a private high school in Calamba because the youth of this town had to go to Laguna High School in Sta. Cruz, to Rural High in Los Baños, or elsewhere to pursue further schooling. Calamba had no secondary school then. Eventually, in 1930, he founded the Laguna Institute.
He suffered from a heart condition, which was the cause of his death on January 13, 1946. His death was a great loss as he could have done more service to humanity. Don Pedro’s demise did not stop his heirs from continuing what he started. They continued to serve the community by offering quality education with a determination to achieve academic excellence.
