Gabriel Custodio was born in Tanza, Cavito, in the Philippines. He learnt the rudiments of painting from an aunt and was later taught by Fernando Amorsolo. Custodio became one of the ‘Conservative Group’ of artists in the Philippines, painting in an academic, traditional style. He went on to teach others who were to become noted artists, including Navarro, Galvez and Dumlao, and won a number of prizes in the 1950s. He exhibited in Australia and the United States in addition to his home country. Custodio painted some fine murals at St George’s Greek Orthodox Church on Makati Avenue. His work is in the collection of the National Gallery of Manila and hangs in the United Nations Headquarters in New York.
