Isidoro Valcárcel Medina (Murcia, 1937) is a Spanish plastic and conceptual artist.

He went to live in Madrid when he was 19 years old, where he studied Architecture and Fine Arts, although he did not finish them.

In 2007 he received the National Prize for Plastic Arts of Spain.In 2015, the documentary I will not write art with a capital letter, directed by Miguel Álvarez-Fernández and Luis Deltell, dedicated to the life and work of he. He received the Velázquez Prize for Plastic Arts in 2015.

In 2019 he premieres his second film work.

His work over more than forty years is endowed with great rigor and coherence. His proposals suppose a committed attitude and away from the commercial aspects of art. His artistic conception can be glimpsed in one of his statements: «Art is a personal action that can serve as an example, but never have an exemplary value.» 6 In this way, for him, art only makes sense when it makes us aware and responsible for a personal reality, usually through the game of art itself.

He begins his work from painting, and his work can be framed in informalism; his only exhibition within this trend was held in 1962 at the Lorca gallery in Madrid. Later, his work falls within objective, constructivist and rational art; in 1967 he was selected for the First Hall of Constructivist Art. In 1968, after a stay in New York, he made contact with minimalism.

From a phase known by himself as «habitable painting», he evolved towards the construction of places through «environements» and «performances». Starting in 1972, his works are carried out mainly in urban spaces and his intervention in large dimensional spaces.
