Career
He was former managing editor of Bannawag, a weekly Ilokano magazine. During his 37-year stint (1961–1998) as senior literary editor at Bannawag, he guided, encouraged and trained young and old Ilokano writers to produce quality Iloko literary works. He was among the recipients of the first ever Philippine-International Theater Institute-National Commission for Culture and the Arts Award for Culture-Friendly Media Institutions.
Hidalgo was responsible for the founding of GUMIL Filipinas (Gunglo dagiti Mannurat nga Ilokano iti Filipinas).
The top national organization of Iloko writers, GUMIL now boasts of chapters in Guam, Greece, California, and Hawaii. Considered by his peers as a "prodigy in Ilokano literature," Hidalgo published in 1969 the now classic Iloko anthology, "Bituen ti Rosales ken Dadduma Pay a Sarita" ("Star of Rosales and Other Stories"), a collection of 20 selected short stories.
This book became, as Iloko literary critics and scholars acknowledge, the "official textbook of contemporary Iloko writers" because of its influence on the serious Iloko writer As editor and translator, he published other anthologies of selected Iloko short stories.
He translated a number of novels and short stories written in German or Japanese into Iloco.
Even as he toiled as literary editor at Bannawag and saw to it that the quality of the literary output improved, he was able to publish in the magazine some 7 novels, 3 novellas, 4 biographies about Virgin Mary, and numerous poems, short stories and essays. His paintings were included in various art exhibits in Metro Manila and in the provinces. Born in Intramuros, Manila, Hidalgo spent his childhood in Rosales, Pangasinan.
They have three daughters: Maria Bituen (b 1970), Patricia Amor (b 1971), and Marie Sol (b 1973).
