Manolo Millares (Las Palmas de Gran Canaria, Canary Islands, 17 January 1926 – Madrid, 14 August 1972) was a Spanish painter. Self-taught as an artist, Millares was introduced to Surrealism in 1948. In 1953, he moved to Madrid and became an abstract painter. In 1957, Millares along with Antonio Saura and Pablo Serrano founded the avant-garde group El Paso (The Step) in Madrid. After showing his work in San Pablo in 1957, Millares' work was introduced to the United States in 1958. He attained an international reputation by the early 1960s, and had a solo show at the Pierre Matisse Gallery in New York in 1961.
In Madrid, Millares was associated with ‘The Informalists’, a group of artists including Antoni Tàpies, Enrique Tábara, Antonio Saura, Laurent Jiménez-Balaguer and Aníbal Villacís among many others who insisted that art should be removed from theory and concept. To these artists, the gesture used to make a painting was all-important. In the 1950s, Millares began to make dramatic collages from found materials, especially burlap.
Relatives include his son Pascual Millares, and other relatives Angel Manuel Millares, Angel Manuel Millares Jr., Javier Millares, Michelle Millares, and Mia Marie Millares.
