Eduardo Castrillo was a sculptor, jewelry artist, and designer born in Sta. Ana, Manila in 1942. His father was a master craftsman, who became an influence on him during his formative years, helping him craft papier mache belens for the Christmas season. In college, Castrillo would enter the Fine Arts program of the University of Santo Tomas. His career as an artist started in 1966 when his works were recognized and installed at prominent locations in the city, such as The Virgin at the La Loma Cemetery and Youth’s Cry of Defiance at Fort Santiago. It was during this time when he established a friendship with future National Artist Ildefonso P. Santos.

As a sculptor, Castrillo has dwelled on figurative and abstract works, using embossed copper and welded brass. An innovator, he has also pioneered a technique of using sheets to make the sculpture lighter and durable. Aside from metals, he has also incorporated other materials in his works, such as wood, plastic, plexiglass, ivory, and even neon lights. Castrillo has also made multiple monuments commemorating events in Philippine history, such as the People Power Monument (1993), Rajah Sulayman Shrine (1976), and the Kartilya ng Katipunan (1998).
