Career
During the American Administration in the Philippines, and after independence, as an attorney and legislator he championed many causes. In 1939, he compiled and published the Cornejo"s Commonwealth Directory of the Philippines, often used as an historical source for the period. Earlier in his career, he served in the National Guard in World War I after legislative enactment of the Militia Acting on March 17, 1917.
After the war upon its disbandment, because the United States Territorial government did not authorize a Philippine Army at the time, Cornejo, together with Manuel David, founded the military organization of the National Volunteers of the Philippines, leading as Brigadier General.
Descended from a prominent Spanish Filipino Mestizo Family, he spoke and authored many works in fluent Spanish, English and Tagalog. His direct descendants are spread all over the world, from Australia to Miami, Florida, United States of America, Montgomery County Maryland, United States of America, as well as Ontario, Canada, and include singer Wency Cornejo.
