Lucio Muñoz was born in Madrid in 1929. He studied at the San Fernando School of Fine Arts, where he became friendly with artists from the realist movement known as 'realismo madrileño', such as Antonio López, the brothers Julio and Francisco López Hernández and his future wife, the painter Amalia Avia. In 1954 he obtained a scholarship to study in Italy, and later –in 1956– in Paris, where he became familiar with the work of artists such as Dubuffet and Soulages. His first one-man exhibition took place in 1957 at the Fernando Fe gallery in Madrid. From that point on he held various solo and collective exhibitions in cities throughout Spain, Europe and America. His work was selected for participation in competitions such as the Venice Biennale and in major international shows in the MoMA and the Guggenheim Museum in New York, among others. He died in Madrid in 1998.
