Benigno Simeón Quiambao Aquino Sr. (September 3, 1894 – December 20, 1947) was a Filipino politician who served as Speaker of the National Assembly of the Japanese-sponsored puppet state in the Philippines from 1943 to 1944.
He was the Director-General of KALIBAPI, a political party established during the Japanese occupation of the Philippines.
His grandson, Benigno S. Aquino III was the 15th President of the Philippines, serving from 2010 to 2016.
Aquino was born in Murcia (now part of Concepcion, Tarlac) in the town of Tarlac to Servillano "Mianong" Aquino, a general in the Philippine Revolution who later served as a member of the Malolos Congress, and Guadalupe Quiambao. He had two siblings: Gonzalo Aquino (1893–??) and Amando Aquino (1896–??), and a half-brother, Herminio Aquino (1949–2021). He studied at the Colegio de San Juan de Letran in Manila and later at the University of Santo Tomas, where he earned his law degree in 1913, and was admitted to the bar the following year.
Aquino was first elected to the Philippine Legislature as a member of the Philippine House of Representatives in 1919 representing the 2nd district of Tarlac. He was reelected to the same position in 1922 and 1925 before winning a Philippine Senate seat in 1928 representing the 3rd Senatorial District comprising the provinces of Bulacan, Nueva Ecija, Pampanga and his home-province of Tarlac. He became part of the Philippine Independence Mission in 1931, which negotiated the terms of obtaining Philippine independence from the United States. During the elections for the Commonwealth of the Philippines government in 1935 he ran again in his district in Tarlac and won, this time as a member of the National Assembly. In 1937, he was appointed by Commonwealth President Manuel L. Quezon as Secretary of Agriculture and Commerce.
Being among the more prominent Commonwealth officials remaining in the country after the Commonwealth government went into exile in 1941, Aquino was among those recruited by the Japanese to form a government. He became the director-general of KALIBAPI and one of the two assistant chairmen of the Preparatory Commission for Philippine Independence. When the Second Philippine Republic was inaugurated, he was elected Speaker of the National Assembly.
In December 1944, as the combined Filipino and American forces continued their advance to liberate the Philippines from Japanese forces, the government of the Second Philippine Republic, which included Aquino, was moved to Baguio. Subsequently, they travelled to Tuguegarao, where they were flown to Japan via Formosa (now Taiwan) and Shanghai, China. On September 15, 1945, while in Nara, Aquino, alongside former President Jose P. Laurel and his son Jose III, was arrested and placed into custody by Americans led by Colonel Turner following the surrender of Japan. They were imprisoned at Yokohama prison and two months later at Sugamo Prison. On July 23, 1946, they were flown back to the Philippines for trial on treason charges by the People's Court.[1] A few weeks later, he was released on bail.
In May 1916, he married Maria Urquico, the daughter of katipunero Antonio Urquico and Justa Valeriano. He had two sons and two daughters with Maria: Antonio Aquino “Tony” (1917–1993), Servillano Aquino II “Billy” (1919–1973), Milagros Aquino “Mila” (1924–2001), and Erlinda Aquino “Linda” (1926–2022).
After Maria died in March 1928, he married Aurora Lampa Aquino (maiden name, granddaughter of Melencio Aquino and Evarista de los Santos and daughter of Agapito de los Santos Aquino and Gerarda Miranda Lampa) on December 6, 1930, with whom he had seven children—Maria Aurora (Maur), Benigno Simeon Jr. (Ninoy), Maria Gerarda (Ditas), Maria Guadalupe (Lupita), Agapito (Butz), Paul, and Maria Teresa (Tessie).[2]
On December 20, 1947, Aquino died of a heart attack at the Rizal Memorial Coliseum in Manila while watching a boxing match.
