Eduardo Ramírez Villamizar (1922-2004) was a Colombian painter and sculptor, a pioneer of abstract and constructive art. His minimalist work has made a significant impact on the continent. In his sculptural installations in public spaces, vertical and angular lines prevail. With few exceptions, he only used primary and neutral colors such as white and black. He worked with iron, concrete, wood, marble, aluminum, cardboard, and paper, exploring soft and hard materials with equal confidence and creativity. He also created murals and three-dimensional reliefs with geometry and the absence of color. He used sculpture to express ideas that could be quickly understood, much like a Japanese poem. He was awarded multiple prizes in Colombia and abroad for his skill with materials, his creativity, and generosity. He was selected by the newspaper El Tiempo as one of the 100 Colombian personalities of the 20th century.
